Bug#533267: release-notes: Purging uninstalled packages

["Karl O. Pinc" <kop@meme.com>]

Package: release-notes
Version: lenny
Severity: normal

Hi,

It almost goes without saying, but at the end of the
upgrade process it can be a good idea to purge the
configuration files of those packages that are no
longer installed.  Something like:

Examine leftover config files:
  aptitude search ~c
And then if all the config files are no longer needed:
  aptitude purge $(aptitude search ~c -F "%p")

Where this can really be important is purging the
old linux kernels.  Sometimes /boot can fill up.

It's probably a good idea to do a aptitude search ~c
before starting the upgrade as well, and either keep
the list for later comparison when the upgrade is
done or cleanup before starting the upgrade.
