  I changed gnabak a little so that it will try to hardlink with backup
from all past dates instead of just the previous ones:

<     push(@args, "--link-dest", "../$_") foreach @history;
---
>     push(@args, "--link-dest", "../".$history[0]) if @history;

  Running gnabak.pl with the --simulate give this rsync invocation for
instance:

command: /usr/bin/rsync -a --rsh ssh -l backup --delete
--delete-excluded --numeric-ids --exclude lost+found
--exclude /praksys/praksys/ --exclude /underware/debian/
--exclude /underware/iso/ --exclude /daily/
--link-dest ../svn_2009-09-24 --link-dest ../svn_2009-09-23
--link-dest ../svn_2009-09-22 --link-dest ../svn_2009-09-19
--link-dest ../svn_2009-09-14 --link-dest ../svn_2009-09-04
--link-dest ../svn_2009-09-03 --link-dest ../svn_2009-09-02
--link-dest ../svn_2009-09-01 svn.gna.org:/var/svn/ svn_2009-09-25


  This should help a lot with missing or half-finished backups, were
gnabak would download old files *again*. We'll confirm tomorrow if at
least I didn't break anything :)
