manpagesection(The APT Group)
This group of options controls general APT behavoir as well as holding the
Ignore Held packages; This global options causes the problem resolver to
ignore held packages in its decision making.
+dit(bf(Clean-Installed))
+Defaults to on. When turned on the autoclean feature will remove any pacakge
+which can no longer be downloaded from the cache. If turned off then
+packages that are locally installed are also excluded from cleaning - but
+note that APT provides no direct means to reinstall them.
+
dit(bf(Immediate-Configure))
Disable Immedate Configuration; This dangerous option disables some
of APT's ordering code to cause it to make fewer dpkg calls. Doing
is very dangerous and may cause package install scripts to fail or worse.
Use at your own risk.
+dit(bf(Force-LoopBreak))
+Never Enable this option unless you -really- know what you are doing. It
+permits APT to temporarily remove an essential package to break a
+Conflicts/Conflicts or Conflicts/Pre-Depend loop between two essential
+packages. SUCH A LOOP SHOULD NEVER EXIST AND IS A GRAVE BUG. This option will
+work if the essential packages are not tar, gzip, libc, dpkg, bash or
+anything that those packages depend on.
+
+dit(bf(Cache-Limit))
+APT uses a fixed size memory mapped cache file to store the 'available'
+information. This sets the size of that cache.
+
dit(bf(Get))
The Get subsection controls the bf(apt-get(8)) tool, please see its
documentation for more information about the options here.
Number of retries to perform. If this is non-zero apt will retry failed
files the given number of times.
+dit(bf(Source-Symlinks))
+Use symlinks for source archives. If set to true then source archives will
+be symlinked when possible instead of copying. True is the default
+
dit(bf(http))
HTTP URIs; http::Proxy is the default http proxy to use. It is in the standard
form of em(http://[[user][:pass]@]host[:port]/). Per host proxies can also
with very large .deb files. Note: Squid 2.0.2 does not support any of
these options.
+The option bf(timeout) sets the timeout timer used by the method, this
+applies to all things including connection timeout and data timeout.
+
One setting is provided to control the pipeline depth in cases where the
remote server is not RFC conforming or buggy (such as Squid 2.0.2)
Acquire::http::Pipeline-Depth can be a value from 0 to 5 indicating how many
dit(bf(ftp))
FTP URis; ftp::Proxy is the default proxy server to use. It is in the
-standard form of em(http://[[user][:pass]@]host[:port]/) and is overriden
+standard form of em(ftp://[[user][:pass]@]host[:port]/) and is overriden
by the ftp_proxy environment variable. To use a ftp proxy you will have to
set the ftp::ProxyLogin script in the configuration file. This entry
specifies the commands to send to tell the proxy server what to connect
-to. Please see em(/usr/doc/apt/examples/apt.conf) for an example of how
+to. Please see em(/usr/doc/apt/examples/configure-index) for an example of how
to do this. The subsitution variables available are $(PROXY_USER),
$(PROXY_PASS), $(SITE_USER), $(SITE_PASS), $(SITE), and $(SITE_PORT).
Each is taken from it's respective URI component.
+The option bf(timeout) sets the timeout timer used by the method, this
+applies to all things including connection timeout and data timeout.
+
Several settings are provided to control passive mode. Generally it is safe
to leave passive mode on, it works in nearly every environment. However some
situations require that passive mode be disabled and port mode ftp used
instead. This can be done globally, for connections that go through a proxy
or for a specific host (See the sample config file for examples)
+
+It is possible to proxy FTP over HTTP by setting the em(ftp_proxy)
+environment variable to a http url - see the discussion of the http method
+above for syntax. You cannot set this in the configuration file and it is
+not recommended to use FTP over HTTP due to its low efficiency.
+
dit(bf(cdrom))
CDROM URIs; the only setting for CDROM URIs is the mount point, cdrom::Mount
which must be the mount point for the CDROM drive as specified in /etc/fstab.
location to place downloaded archives, bf(Dir::Cache::archives). Like
bf(Dir::State) the default directory is contained in bf(Dir::Cache)
-bf(Dir::Etc) contains the location of configuration files, bd(sourcelist)
+bf(Dir::Etc) contains the location of configuration files, bf(sourcelist)
gives the location of the sourcelist and bf(main) is the default configuration
file (setting has no effect)
startdit()
dit(bf(Clean))
Cache Clean mode; this value may be one of always, auto, prompt and never.
-Currently always and auto are identical but their meanings may diverge in
-future to have auto only clean useless archives and always clean all archives.
+always will remove all archives after they have been downloaded while auto
+will only remove things that are no longer downloadable (replaced with a new
+version for instance)
dit(bf(Options))
The contents of this variable is passed to bf(apt-get(8)) as command line
bf(Options) this must be specified in list notation. The commands
are invoked in order using /bin/sh, should any fail APT will abort.
+dit(bf(Pre-Install-Pkgs))
+This is a list of shell commands to run before invoking dpkg. Like
+bf(Options) this must be specified in list notation. The commands
+are invoked in order using /bin/sh, should any fail APT will abort.
+Apt will pass to the commands on standard input the filenames of all

dit(bf(Run-Directory))
APT chdirs to this directory before invoking dpkg, the default is /.
