As my guest OS (Debian) was filling /var/cache/apt/* with MB's of stuff, I have modified /etc/fstab and mounted all /var/cache/apt and children directories on tmpfs, then I have installed/uninstalled a few packages. I have compared the size of the temp snapshot file with the one generated before and I have found no differences. I wonder if that means something.
