Re: Debian derivatives census: removing old patches

[Anastasia Tsikoza <anastasia.tsikoza@gmail.com>]

I am pleased to announce that the patches generation is now re-enabled.
We have freed a significant amount of disk space after removing 
obsolete files and duplicates.

The cleanup included:

    * removing old patches of active derivatives and all the 
      corresponding dsc and non-dsc parts, lsdiffs and changelogs
    * detecting files of packages merged into Debian and replacing
      them with symlinks
    * removing packages not derived from any Debian package that 
      are no longer present in any derivative's apt repository

Also patches now have to be kept for a year starting from the day when 
they became obsolete. Small patches where the only change is in 
debian/changelog will be kept for 3 months. Patches and packages of 
inactive derivatives have no expiration date for now and won't be 
removed.

Disk usage after generating all actual patches:

    /srv/qa.debian.org          554G  439G   89G  84%
