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.
