software. +By downloading or using this software, you are agreeing to be bound by +the terms of this License. If you do not or cannot agree to the terms +of this License, please do not download or use the software. + +1. General; Definitions. This License applies to any program or other +work which Apple Computer, Inc. ("Apple") makes publicly available and +which contains a notice placed by Apple identifying such program or +work as "Original Code" and stating that it is subject to the terms of +this Apple Public Source License version 2.0 ("License"). As used in +this License: + +1.1 "Applicable Patent Rights" mean: (a) in the case where Apple is +the grantor of rights, (i) claims of patents that are now or hereafter +acquired, owned by or assigned to Apple and (ii) that cover subject +matter contained in the Original Code, but only to the extent +necessary to use, reproduce and/or distribute the Original Code +without infringement; and (b) in the case where You are the grantor of +rights, (i) claims of patents that are now or hereafter acquired, +owned by or assigned to You and (ii) that cover subject matter in Your +Modifications, taken alone or in combination with Original Code. + +1.2 "Contributor" means any person or entity that creates or +contributes to the creation of Modifications. + +1.3 "Covered Code" means the Original Code, Modifications, the +combination of Original Code and any Modifications, and/or any +respective portions thereof. + +1.4 "Externally Deploy" means: (a) to sublicense, distribute or +otherwise make Covered Code available, directly or indirectly, to +anyone other than You; and/or (b) to use Covered Code, alone or as +part of a Larger Work, in any way to provide a service, including but +not limited to delivery of content, through electronic communication +with a client other than You. + +1.5 "Larger Work" means a work which combines Covered Code or portions +thereof with code not governed by the terms of this License. + +1.6 "Modifications" mean any addition to, deletion from, and/or change +to, the substance and/or structure of the Original Code, any previous +Modifications, the combination of Original Code and any previous +Modifications, and/or any respective portions thereof. When code is +released as a series of files, a Modification is: (a) any addition to +or deletion from the contents of a file containing Covered Code; +and/or (b) any new file or other representation of computer program +statements that contains any part of Covered Code. + +1.7 "Original Code" means (a) the Source Code of a program or other +work as originally made available by Apple under this License, +including the Source Code of any updates or upgrades to such programs +or works made available by Apple under this License, and that has been +expressly identified by Apple as such in the header file(s) of such +work; and (b) the object code compiled from such Source Code and +originally made available by Apple under this License. + +1.8 "Source Code" means the human readable form of a program or other +work that is suitable for making modifications to it, including all +modules it contains, plus any associated interface definition files, +scripts used to control compilation and installation of an executable +(object code). + +1.9 "You" or "Your" means an individual or a legal entity exercising +rights under this License. For legal entities, "You" or "Your" +includes any entity which controls, is controlled by, or is under +common control with, You, where "control" means (a) the power, direct +or indirect, to cause the direction or management of such entity, +whether by contract or otherwise, or (b) ownership of fifty percent +(50%) or more of the outstanding shares or beneficial ownership of +such entity. + +2. Permitted Uses; Conditions & Restrictions. Subject to the terms +and conditions of this License, Apple hereby grants You, effective on +the date You accept this License and download the Original Code, a +world-wide, royalty-free, non-exclusive license, to the extent of +Apple's Applicable Patent Rights and copyrights covering the Original +Code, to do the following: + +2.1 Unmodified Code. You may use, reproduce, display, perform, +internally distribute within Your organization, and Externally Deploy +verbatim, unmodified copies of the Original Code, for commercial or +non-commercial purposes, provided that in each instance: + +(a) You must retain and reproduce in all copies of Original Code the +copyright and other proprietary notices and disclaimers of Apple as +they appear in the Original Code, and keep intact all notices in the +Original Code that refer to this License; and + +(b) You must include a copy of this License with every copy of Source +Code of Covered Code and documentation You distribute or Externally +Deploy, and You may not offer or impose any terms on such Source Code +that alter or restrict this License or the recipients' rights +hereunder, except as permitted under Section 6. + +2.2 Modified Code. You may modify Covered Code and use, reproduce, +display, perform, internally distribute within Your organization, and +Externally Deploy Your Modifications and Covered Code, for commercial +or non-commercial purposes, provided that in each instance You also +meet all of these conditions: + +(a) You must satisfy all the conditions of Section 2.1 with respect to +the Source Code of the Covered Code; + +(b) You must duplicate, to the extent it does not already exist, the +notice in Exhibit A in each file of the Source Code of all Your +Modifications, and cause the modified files to carry prominent notices +stating that You changed the files and the date of any change; and + +(c) If You Externally Deploy Your Modifications, You must make +Source Code of all Your Externally Deployed Modifications either +available to those to whom You have Externally Deployed Your +Modifications, or publicly available. Source Code of Your Externally +Deployed Modifications must be released under the terms set forth in +this License, including the license grants set forth in Section 3 +below, for as long as you Externally Deploy the Covered Code or twelve +(12) months from the date of initial External Deployment, whichever is +longer. You should preferably distribute the Source Code of Your +Externally Deployed Modifications electronically (e.g. download from a +web site). + +2.3 Distribution of Executable Versions. In addition, if You +Externally Deploy Covered Code (Original Code and/or Modifications) in +object code, executable form only, You must include a prominent +notice, in the code itself as well as in related documentation, +stating that Source Code of the Covered Code is available under the +terms of this License with information on how and where to obtain such +Source Code. + +2.4 Third Party Rights. You expressly acknowledge and agree that +although Apple and each Contributor grants the licenses to their +respective portions of the Covered Code set forth herein, no +assurances are provided by Apple or any Contributor that the Covered +Code does not infringe the patent or other intellectual property +rights of any other entity. Apple and each Contributor disclaim any +liability to You for claims brought by any other entity based on +infringement of intellectual property rights or otherwise. As a +condition to exercising the rights and licenses granted hereunder, You +hereby assume sole responsibility to secure any other intellectual +property rights needed, if any. For example, if a third party patent +license is required to allow You to distribute the Covered Code, it is +Your responsibility to acquire that license before distributing the +Covered Code. + +3. Your Grants. In consideration of, and as a condition to, the +licenses granted to You under this License, You hereby grant to any +person or entity receiving or distributing Covered Code under this +License a non-exclusive, royalty-free, perpetual, irrevocable license, +under Your Applicable Patent Rights and other intellectual property +rights (other than patent) owned or controlled by You, to use, +reproduce, display, perform, modify, sublicense, distribute and +Externally Deploy Your Modifications of the same scope and extent as +Apple's licenses under Sections 2.1 and 2.2 above. + +4. Larger Works. You may create a Larger Work by combining Covered +Code with other code not governed by the terms of this License and +distribute the Larger Work as a single product. In each such instance, +You must make sure the requirements of this License are fulfilled for +the Covered Code or any portion thereof. + +5. Limitations on Patent License. Except as expressly stated in +Section 2, no other patent rights, express or implied, are granted by +Apple herein. Modifications and/or Larger Works may require additional +patent licenses from Apple which Apple may grant in its sole +discretion. + +6. Additional Terms. You may choose to offer, and to charge a fee for, +warranty, support, indemnity or liability obligations and/or other +rights consistent with the scope of the license granted herein +("Additional Terms") to one or more recipients of Covered Code. +However, You may do so only on Your own behalf and as Your sole +responsibility, and not on behalf of Apple or any Contributor. You +must obtain the recipient's agreement that any such Additional Terms +are offered by You alone, and You hereby agree to indemnify, defend +and hold Apple and every Contributor harmless for any liability +incurred by or claims asserted against Apple or such Contributor by +reason of any such Additional Terms. + +7. Versions of the License. Apple may publish revised and/or new +versions of this License from time to time. Each version will be given +a distinguishing version number. Once Original Code has been published +under a particular version of this License, You may continue to use it +under the terms of that version. You may also choose to use such +Original Code under the terms of any subsequent version of this +License published by Apple. No one other than Apple has the right to +modify the terms applicable to Covered Code created under this +License. + +8. NO WARRANTY OR SUPPORT. The Covered Code may contain in whole or in +part pre-release, untested, or not fully tested works. The Covered +Code may contain errors that could cause failures or loss of data, and +may be incomplete or contain inaccuracies. You expressly acknowledge +and agree that use of the Covered Code, or any portion thereof, is at +Your sole and entire risk. THE COVERED CODE IS PROVIDED "AS IS" AND +WITHOUT WARRANTY, UPGRADES OR SUPPORT OF ANY KIND AND APPLE AND +APPLE'S LICENSOR(S) (COLLECTIVELY REFERRED TO AS "APPLE" FOR THE +PURPOSES OF SECTIONS 8 AND 9) AND ALL CONTRIBUTORS EXPRESSLY DISCLAIM +ALL WARRANTIES AND/OR CONDITIONS, EXPRESS OR IMPLIED, INCLUDING, BUT +NOT LIMITED TO, THE IMPLIED WARRANTIES AND/OR CONDITIONS OF +MERCHANTABILITY, OF SATISFACTORY QUALITY, OF FITNESS FOR A PARTICULAR +PURPOSE, OF ACCURACY, OF QUIET ENJOYMENT, AND NONINFRINGEMENT OF THIRD +PARTY RIGHTS. APPLE AND EACH CONTRIBUTOR DOES NOT WARRANT AGAINST +INTERFERENCE WITH YOUR ENJOYMENT OF THE COVERED CODE, THAT THE +FUNCTIONS CONTAINED IN THE COVERED CODE WILL MEET YOUR REQUIREMENTS, +THAT THE OPERATION OF THE COVERED CODE WILL BE UNINTERRUPTED OR +ERROR-FREE, OR THAT DEFECTS IN THE COVERED CODE WILL BE CORRECTED. NO +ORAL OR WRITTEN INFORMATION OR ADVICE GIVEN BY APPLE, AN APPLE +AUTHORIZED REPRESENTATIVE OR ANY CONTRIBUTOR SHALL CREATE A WARRANTY. +You acknowledge that the Covered Code is not intended for use in the +operation of nuclear facilities, aircraft navigation, communication +systems, or air traffic control machines in which case the failure of +the Covered Code could lead to death, personal injury, or severe +physical or environmental damage. + +9. LIMITATION OF LIABILITY. TO THE EXTENT NOT PROHIBITED BY LAW, IN NO +EVENT SHALL APPLE OR ANY CONTRIBUTOR BE LIABLE FOR ANY INCIDENTAL, +SPECIAL, INDIRECT OR CONSEQUENTIAL DAMAGES ARISING OUT OF OR RELATING +TO THIS LICENSE OR YOUR USE OR INABILITY TO USE THE COVERED CODE, OR +ANY PORTION THEREOF, WHETHER UNDER A THEORY OF CONTRACT, WARRANTY, +TORT (INCLUDING NEGLIGENCE), PRODUCTS LIABILITY OR OTHERWISE, EVEN IF +APPLE OR SUCH CONTRIBUTOR HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH +DAMAGES AND NOTWITHSTANDING THE FAILURE OF ESSENTIAL PURPOSE OF ANY +REMEDY. SOME JURISDICTIONS DO NOT ALLOW THE LIMITATION OF LIABILITY OF +INCIDENTAL OR CONSEQUENTIAL DAMAGES, SO THIS LIMITATION MAY NOT APPLY +TO YOU. In no event shall Apple's total liability to You for all +damages (other than as may be required by applicable law) under this +License exceed the amount of fifty dollars ($50.00). + +10. Trademarks. This License does not grant any rights to use the +trademarks or trade names "Apple", "Apple Computer", "Mac", "Mac OS", +"QuickTime", "QuickTime Streaming Server" or any other trademarks, +service marks, logos or trade names belonging to Apple (collectively +"Apple Marks") or to any trademark, service mark, logo or trade name +belonging to any Contributor. You agree not to use any Apple Marks in +or as part of the name of products derived from the Original Code or +to endorse or promote products derived from the Original Code other +than as expressly permitted by and in strict compliance at all times +with Apple's third party trademark usage guidelines which are posted +at http://www.apple.com/legal/guidelinesfor3rdparties.html. + +11. Ownership. Subject to the licenses granted under this License, +each Contributor retains all rights, title and interest in and to any +Modifications made by such Contributor. Apple retains all rights, +title and interest in and to the Original Code and any Modifications +made by or on behalf of Apple ("Apple Modifications"), and such Apple +Modifications will not be automatically subject to this License. Apple +may, at its sole discretion, choose to license such Apple +Modifications under this License, or on different terms from those +contained in this License or may choose not to license them at all. + +12. Termination. + +12.1 Termination. This License and the rights granted hereunder will +terminate: + +(a) automatically without notice from Apple if You fail to comply with +any term(s) of this License and fail to cure such breach within 30 +days of becoming aware of such breach; + +(b) immediately in the event of the circumstances described in Section +13.5(b); or + +(c) automatically without notice from Apple if You, at any time during +the term of this License, commence an action for patent infringement +against Apple; provided that Apple did not first commence +an action for patent infringement against You in that instance. + +12.2 Effect of Termination. Upon termination, You agree to immediately +stop any further use, reproduction, modification, sublicensing and +distribution of the Covered Code. All sublicenses to the Covered Code +which have been properly granted prior to termination shall survive +any termination of this License. Provisions which, by their nature, +should remain in effect beyond the termination of this License shall +survive, including but not limited to Sections 3, 5, 8, 9, 10, 11, +12.2 and 13. No party will be liable to any other for compensation, +indemnity or damages of any sort solely as a result of terminating +this License in accordance with its terms, and termination of this +License will be without prejudice to any other right or remedy of +any party. + +13. Miscellaneous. + +13.1 Government End Users. The Covered Code is a "commercial item" as +defined in FAR 2.101. Government software and technical data rights in +the Covered Code include only those rights customarily provided to the +public as defined in this License. This customary commercial license +in technical data and software is provided in accordance with FAR +12.211 (Technical Data) and 12.212 (Computer Software) and, for +Department of Defense purchases, DFAR 252.227-7015 (Technical Data -- +Commercial Items) and 227.7202-3 (Rights in Commercial Computer +Software or Computer Software Documentation). Accordingly, all U.S. +Government End Users acquire Covered Code with only those rights set +forth herein. + +13.2 Relationship of Parties. This License will not be construed as +creating an agency, partnership, joint venture or any other form of +legal association between or among You, Apple or any Contributor, and +You will not represent to the contrary, whether expressly, by +implication, appearance or otherwise. + +13.3 Independent Development. Nothing in this License will impair +Apple's right to acquire, license, develop, have others develop for +it, market and/or distribute technology or products that perform the +same or similar functions as, or otherwise compete with, +Modifications, Larger Works, technology or products that You may +develop, produce, market or distribute. + +13.4 Waiver; Construction. Failure by Apple or any Contributor to +enforce any provision of this License will not be deemed a waiver of +future enforcement of that or any other provision. Any law or +regulation which provides that the language of a contract shall be +construed against the drafter will not apply to this License. + +13.5 Severability. (a) If for any reason a court of competent +jurisdiction finds any provision of this License, or portion thereof, +to be unenforceable, that provision of the License will be enforced to +the maximum extent permissible so as to effect the economic benefits +and intent of the parties, and the remainder of this License will +continue in full force and effect. (b) Notwithstanding the foregoing, +if applicable law prohibits or restricts You from fully and/or +specifically complying with Sections 2 and/or 3 or prevents the +enforceability of either of those Sections, this License will +immediately terminate and You must immediately discontinue any use of +the Covered Code and destroy all copies of it that are in your +possession or control. + +13.6 Dispute Resolution. Any litigation or other dispute resolution +between You and Apple relating to this License shall take place in the +Northern District of California, and You and Apple hereby consent to +the personal jurisdiction of, and venue in, the state and federal +courts within that District with respect to this License. The +application of the United Nations Convention on Contracts for the +International Sale of Goods is expressly excluded. + +13.7 Entire Agreement; Governing Law. This License constitutes the +entire agreement between the parties with respect to the subject +matter hereof. This License shall be governed by the laws of the +United States and the State of California, except that body of +California law concerning conflicts of law. + +Where You are located in the province of Quebec, Canada, the following +clause applies: The parties hereby confirm that they have requested +that this License and all related documents be drafted in English. Les +parties ont exige que le present contrat et tous les documents +connexes soient rediges en anglais. + +EXHIBIT A. + +"Portions Copyright (c) 1999-2003 Apple Computer, Inc.

It uses +those values to create a `Makefile' in each directory of the package. +It may also create one or more `.h' files containing system-dependent +definitions. Finally, it creates a shell script `config.status' that +you can run in the future to recreate the current configuration, and a +file `config.log' containing compiler output (useful mainly for +debugging `configure'). + + It can also use an optional file (typically called `config.cache' +and enabled with `--cache-file=config.cache' or simply `-C') that saves +the results of its tests to speed up reconfiguring. (Caching is +disabled by default to prevent problems with accidental use of stale +cache files.) + + If you need to do unusual things to compile the package, please try +to figure out how `configure' could check whether to do them, and mail +diffs or instructions to the address given in the `README' so they can +be considered for the next release. If you are using the cache, and at +some point `config.cache' contains results you don't want to keep, you +may remove or edit it. + + The file `configure.ac' (or `configure.in') is used to create +`configure' by a program called `autoconf'. You only need +`configure.ac' if you want to change it or regenerate `configure' using +a newer version of `autoconf'. + +The simplest way to compile this package is: + + 1. `cd' to the directory containing the package's source code and type + `./configure' to configure the package for your system. If you're + using `csh' on an old version of System V, you might need to type + `sh ./configure' instead to prevent `csh' from trying to execute + `configure' itself. + + Running `configure' takes awhile. While running, it prints some + messages telling which features it is checking for. + + 2. Type `make' to compile the package. + + 3. Optionally, type `make check' to run any self-tests that come with + the package. + + 4. Type `make install' to install the programs and any data files and + documentation. + + 5. You can remove the program binaries and object files from the + source code directory by typing `make clean'. To also remove the + files that `configure' created (so you can compile the package for + a different kind of computer), type `make distclean'. There is + also a `make maintainer-clean' target, but that is intended mainly + for the package's developers. If you use it, you may have to get + all sorts of other programs in order to regenerate files that came + with the distribution. + +Compilers and Options +===================== + + Some systems require unusual options for compilation or linking that +the `configure' script does not know about. Run `./configure --help' +for details on some of the pertinent environment variables. + + You can give `configure' initial values for configuration parameters +by setting variables in the command line or in the environment. Here +is an example: + + ./configure CC=c89 CFLAGS=-O2 LIBS=-lposix + + *Note Defining Variables::, for more details. + +Compiling For Multiple Architectures +==================================== + + You can compile the package for more than one kind of computer at the +same time, by placing the object files for each architecture in their +own directory. To do this, you must use a version of `make' that +supports the `VPATH' variable, such as GNU `make'. `cd' to the +directory where you want the object files and executables to go and run +the `configure' script. `configure' automatically checks for the +source code in the directory that `configure' is in and in `..'. + + If you have to use a `make' that does not support the `VPATH' +variable, you have to compile the package for one architecture at a +time in the source code directory. After you have installed the +package for one architecture, use `make distclean' before reconfiguring +for another architecture. + +Installation Names +================== + + By default, `make install' will install the package's files in +`/usr/local/bin', `/usr/local/man', etc. You can specify an +installation prefix other than `/usr/local' by giving `configure' the +option `--prefix=PATH'. + + You can specify separate installation prefixes for +architecture-specific files and architecture-independent files. If you +give `configure' the option `--exec-prefix=PATH', the package will use +PATH as the prefix for installing programs and libraries. +Documentation and other data files will still use the regular prefix. + + In addition, if you use an unusual directory layout you can give +options like `--bindir=PATH' to specify different values for particular +kinds of files. Run `configure --help' for a list of the directories +you can set and what kinds of files go in them. + + If the package supports it, you can cause programs to be installed +with an extra prefix or suffix on their names by giving `configure' the +option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'. + +Optional Features +================= + + Some packages pay attention to `--enable-FEATURE' options to +`configure', where FEATURE indicates an optional part of the package. +They may also pay attention to `--with-PACKAGE' options, where PACKAGE +is something like `gnu-as' or `x' (for the X Window System). The +`README' should mention any `--enable-' and `--with-' options that the +package recognizes. + + For packages that use the X Window System, `configure' can usually +find the X include and library files automatically, but if it doesn't, +you can use the `configure' options `--x-includes=DIR' and +`--x-libraries=DIR' to specify their locations. + +Specifying the System Type +========================== + + There may be some features `configure' cannot figure out +automatically, but needs to determine by the type of machine the package +will run on. Usually, assuming the package is built to be run on the +_same_ architectures, `configure' can figure that out, but if it prints +a message saying it cannot guess the machine type, give it the +`--build=TYPE' option. TYPE can either be a short name for the system +type, such as `sun4', or a canonical name which has the form: + + CPU-COMPANY-SYSTEM + +where SYSTEM can have one of these forms: + + OS KERNEL-OS + + See the file `config.sub' for the possible values of each field. If +`config.sub' isn't included in this package, then this package doesn't +need to know the machine type. + + If you are _building_ compiler tools for cross-compiling, you should +use the `--target=TYPE' option to select the type of system they will +produce code for. + + If you want to _use_ a cross compiler, that generates code for a +platform different from the build platform, you should specify the +"host" platform (i.e., that on which the generated programs will +eventually be run) with `--host=TYPE'. + +Sharing Defaults +================ + + If you want to set default values for `configure' scripts to share, +you can create a site shell script called `config.site' that gives +default values for variables like `CC', `cache_file', and `prefix'. +`configure' looks for `PREFIX/share/config.site' if it exists, then +`PREFIX/etc/config.site' if it exists. Or, you can set the +`CONFIG_SITE' environment variable to the location of the site script. +A warning: not all `configure' scripts look for a site script. + +Defining Variables +================== + + Variables not defined in a site shell script can be set in the +environment passed to `configure'. However, some packages may run +configure again during the build, and the customized values of these +variables may be lost. In order to avoid this problem, you should set +them in the `configure' command line, using `VAR=value'. For example: + + ./configure CC=/usr/local2/bin/gcc + +will cause the specified gcc to be used as the C compiler (unless it is +overridden in the site shell script). + +`configure' Invocation +====================== + + `configure' recognizes the following options to control how it +operates. + +`--help' +`-h' + Print a summary of the options to `configure', and exit. + +`--version' +`-V' + Print the version of Autoconf used to generate the `configure' + script, and exit. + +`--cache-file=FILE' + Enable the cache: use and save the results of the tests in FILE, + traditionally `config.cache'. FILE defaults to `/dev/null' to + disable caching. + +`--config-cache' +`-C' + Alias for `--cache-file=config.cache'. + +`--quiet' +`--silent' +`-q' + Do not print messages saying which checks are being made. To + suppress all normal output, redirect it to `/dev/null' (any error + messages will still be shown). + +`--srcdir=DIR' + Look for the package's source code in directory DIR. Usually + `configure' can determine that directory automatically. + +`configure' also accepts some other, not widely useful, options. Run +`configure --help' for more details. + diff --git a/launchd/Makefile.am b/launchd/Makefile.am new file mode 100644 index 0000000..af437a6 --- /dev/null +++ b/launchd/Makefile.am @@ -0,0 +1 @@ +SUBDIRS = src diff --git a/launchd/Makefile.in b/launchd/Makefile.in new file mode 100644 index 0000000..613b3bf --- /dev/null +++ b/launchd/Makefile.in @@ -0,0 +1,397 @@ +# Makefile.in generated by automake 1.6.3 from Makefile.am. +# @configure_input@ + +# Copyright 1994, 1995, 1996, 1997, 1998, 1999, 2000, 2001, 2002 +# Free Software Foundation, Inc. +# This Makefile.in is free software;

A typical bundle provides a single service. Two bundles may not provide the same service; should multiple bundles which provide the same service be installed on a system, the first one encountered will be run, while the others will be disabled. It is therefore undesireable to provide multiple services in a single bundle unless they are co-dependent, as the overriding of one will effectively override all services in a given bundle (see also "Search Paths for Startup Items").\ +\ + Requires and Uses comprise the primary method for sorting bundles into the startup order. Requires is an array of services, provided by other bundles, that must be successfully started before the bundle can be run. If no such service is provided by any other bundle, the requiring bundle will not run. Uses is similar to Requires in that the bundle will attempt wait for the listed services before running, but it will still launch even if no such service can be provided by another bundle.\ +\ + OrderPreference provides a hint as to the ordering used when a set of bundles are all ready to load.

That is, if multiple items are prioritized equally given the above constraints, there is no rule for which starts first. You must use the dependency mechanism to ensure the correct dependencies have been met. Note also that OrderPreference is merely a suggestion, and that SystemStarter may opt to disregard it. In particular, startup items are run parallel, and items which have dependencies met will be run without waiting for items of a lower OrderPreference to complete.\ +\ + Description is a general-use string describing the item, for use by Admin tools.

Each Darwin +and Mac OS X login creates a unique bootstrap subset context to contain login specific +Mach port registrations with the bootstrap server. All such registrations performed +within the context of that subset are only visible to other processes within that +context or subsequent subsets of it. Therefore, a Mach port based service/daemon +launched within a login context will not be visible to other such contexts. +.Pp +To override this, a root user can use the +.Nm +utility to launch the program within the same bootstrap context as all other +StartupItems. All subsequent Mach port bootstrap registrations perfomed by the program +will be visible system-wide. +.Sh NOTES +All bootstrap port lookups will also be resticted +to the StartupItem context.

In this case, requests sent to the + * bound port will be queued until a server has checked-in and can satisfy the + * request. + * + * 2. Bindings can be established dynamically via a "register" request. In + * this case, the register request provides bootstrap with a name and send + * rights for a port. Bootstrap will provide send rights for the bound port + * to any requestor via the lookup request. + * + * Bootstrap provides its service port to descendant tasks via the Mach + * "bootstrap" special task port. All direct descendants of bootstrap receive + * a "privileged" bootstrap service port. System services that initiate + * untrusted tasks should replace the Mach bootstrap task special port with + * a subset bootstrap port to prevent them from infecting the namespace. + * + * The bootstrap server creates a "backup" port for each service that it + * creates. This is used to detect when a checked out service is no longer + * being served. The bootstrap server regains all rights to the port and + * it is marked available for check-out again. This allows crashed servers to + * resume service to previous clients. Lookup's on this named port will + * continue to be serviced by bootstrap while holding receive rights for the + * bound port. A client may detect that the service is inactive via the + * bootstrap status request. If an inactive service re-registers rather + * than "checking-in" the original bound port is destroyed. + * + * The status of a named service may be obtained via the "status" request. + * A service is "active" if a name-port binding exists and receive rights + * to the bound port are held by a task other than bootstrap. + * + * The bootstrap server may also (re)start server processes associated with + * with a set of services.
