Hi Jurriaan,

I use a cron script & log the output of the following programs daily:

aptitude search '~i'
dpkg --get-selections

With these logs & apropriate backups I can restore my system to it's previous 
state, whether it's rolling back an upgrade or restoring from a crash. I 
would think that something similar would work for you.
