Or, use btrfs. Put your / onto a subvolume named sys-current, and have the following cronjob: # btrfs subv snap sys-current backups/sys-`date +%Y-%m-%d` Whenever shit happens, such as, say, an upload of xorg that takes two weeks for nvidia drivers to get back into a functional state, you do: # mv sys-current sys-broken && btrfs subv snap backups/sys-2015-03-07 sys-current then reboot[1]. Even if things broke so bad you can't boot, simply edit the grub entry to include subvol=backups/sys-2015-03-07 on the kernel's commandline and you're set. Such a scheme makes using unstable so much nicer that I wonder why it's not an option in the d-i. Perhaps we should discuss it[2] and implement it post-jessie? [1]. Can't delete the bad version immediately as you're using it currently. [2]. Besides separate /home (duh), you'll want to reduce the size of backups by separating out /var/cache, make sure noatime is set, etc. -- // If you believe in so-called "intellectual property", please immediately // cease using counterfeit alphabets.
