6473 msgid "Anatomy of the Package System"
6479 "The Debian packaging system has a large amount of information associated "
6480 "with each package to help assure that it integrates cleanly and easily into "
6481 "the system. The most prominent of its features is the dependency system."
6487 "The dependency system allows individual programs to make use of shared "
6488 "elements in the system such as libraries. It simplifies placing infrequently "
6489 "used portions of a program in separate packages to reduce the number of "
6490 "things the average user is required to install. Also, it allows for choices "
6491 "in mail transport agents, X servers and so on."
6497 "The first step to understanding the dependency system is to grasp the "
6498 "concept of a simple dependency. The meaning of a simple dependency is that a "
6499 "package requires another package to be installed at the same time to work "
6506 "For instance, mailcrypt is an emacs extension that aids in encrypting email "
6507 "with GPG. Without GPGP installed mailcrypt is useless, so mailcrypt has a "
6508 "simple dependency on GPG. Also, because it is an emacs extension it has a "
6509 "simple dependency on emacs, without emacs it is completely useless."
6515 "The other important dependency to understand is a conflicting dependency. It "
6516 "means that a package, when installed with another package, will not work and "
6517 "may possibly be extremely harmful to the system. As an example consider a "
6518 "mail transport agent such as sendmail, exim or qmail. It is not possible to "
6519 "have two mail transport agents installed because both need to listen to the "
6520 "network to receive mail. Attempting to install two will seriously damage the "
6521 "system so all mail transport agents have a conflicting dependency with all "
6522 "other mail transport agents."
6528 "As an added complication there is the possibility for a package to pretend "
6529 "to be another package. Consider that exim and sendmail for many intents are "
6530 "identical, they both deliver mail and understand a common interface. Hence, "
6531 "the package system has a way for them to declare that they are both mail-"
6532 "transport-agents. So, exim and sendmail both declare that they provide a "
6533 "mail-transport-agent and other packages that need a mail transport agent "
6534 "depend on mail-transport-agent. This can add a great deal of confusion when "
6535 "trying to manually fix packages."
6541 "At any given time a single dependency may be met by packages that are "
6542 "already installed or it may not be. APT attempts to help resolve dependency "
6543 "issues by providing a number of automatic algorithms that help in selecting "
6544 "packages for installation."

7218 "Normally APT requires direct access to a Debian archive, either from a local "
7219 "media or through a network. Another common complaint is that a Debian "
7220 "machine is on a slow link, such as a modem and another machine has a very "
7221 "fast connection but they are physically distant."
7227 "The solution to this is to use large removable media such as a Zip disc or a "
7228 "SuperDisk disc. These discs are not large enough to store the entire Debian "
7229 "archive but can easily fit a subset large enough for most users. The idea is "
7230 "to use APT to generate a list of packages that are required and then fetch "
7231 "them onto the disc using another machine with good connectivity. It is even "
7232 "possible to use another Debian machine with APT or to use a completely "
7233 "different OS and a download tool like wget. Let <em>remote host</em> mean "
7234 "the machine downloading the packages, and <em>target host</em> the one with "
7235 "bad or no connection."
7241 "This is achieved by creatively manipulating the APT configuration file. The "
7242 "essential premise to tell APT to look on a disc for it's archive files. Note "
