NAME
upgrade-system.conf - upgrade-system(8) configuration file
DESCRIPTION
upgrade-system.conf is the configuration file for the upgrade-system(8)
Debian administration utility. This file specifies options to be passed
to apt-get(8) and deborphan(1).
Lines starting with a hash mark ("#") and empty lines are ignored.
EXAMPLE
The configuration file contains three variables:
CLEANOPTS
This variable is used to pass the command line option to apt-get(8), to
determine whether the autoclean or clean action will be performed. For
example:
CLEANOPTS="clean"
Consult the apt-get(8) manual page to check which options are available
for any particular APT version, before setting this variable.
UPGRADEOPTS
This variable is used to pass command line options to apt-get(8) and to
determine whether the dist-upgrade or upgrade action will be performed.
For example:
UPGRADEOPTS="dist-upgrade"
Consult the apt-get(8) manual page to check which options are available
for any particular APT version, before setting this variable.
ORPHANOPTS
This variable is used to pass command line options to deborphan(1), for
selecting the orphaning operations. For example:
ORPHANOPTS="--guess-all --libdevel --priority=3"
One should read the deborphan(1), manual page to check which options
are available for any particular version, before setting this variable.
SECURITY
Because upgrade-system is an APT front-end, all precautions relating to
APT configuration should be observed. Special attention is required at:
/etc/apt/preferences
To prevent untested packages from overwriting stable ones, setting this
combination of APT preferences is recommended:
Package: *
Pin: release a=stable
Pin-Priority: 990
Package: *
Pin: release a=testing
Pin-Priority: 500
Package: *
Pin: release a=unstable
Pin-Priority: 99
Package: *
Pin: release a=experimental
Pin-Priority: -1
This enforces a priority to packages from Stable, yet still allows ones
from Testing, Unstable or Experimental to get installed via appropriate
apt-get(8) options to override the default release.
deborphan
Certain combinations of deborphan(1) options purge a dangerous quantity
of packages, potentially leaving a system in a severely crippled state.
