Thanks for your well thought reply and advice. I have already applied your suggestions on the pinning strategy.
I knew already how to filter with aptitude, but I didn't know the reference, thank you for the information. Some days ago I updated my basement pc from Jessie to Beowulf and It was all messed up. I managed to recover it, so I guess, if something happens to the one I am asking about, I will (hopefully) be able to recover it too :) Cheers!
