manpagesection(The APT Group)
This group of options controls general APT behavoir as well as holding the
options for all of the tools.
Ignore Held packages; This global options causes the problem resolver to
ignore held packages in its decision making.
+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
+so may be necessary on some extremely slow single user systems but
+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, bash or anything that
+those packages depend on.

+
+One setting is provided to control the pipeline depth in cases where the

+Acquire::http::Pipeline-Depth can be a value from 0 to 5 indicating how many
+outstanding requests APT should send.
+
+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
+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 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.
+
+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)
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.
+It is possible to provide alternate mount and unmount commands if your
+mount point cannot be listed in the fstab (such as an SMB mount). The syntax
+is to put "/cdrom/"::Mount "foo"; within the cdrom block. It is important to
+have the trailing slash. Unmount commands can be specified using UMount.
