I am not so worried about this case. The system is running on a UPS, and if necessary, I can restore the whole system from backup. Also, the hard drives I mentioned are actually virtual drives allocated as pieces of a large RAID-6 array. > Also, when different directory trees gets filled up to 100% different > kind of bad stuff will happen.

In this case, I am the only user, and the system serves just one purpose. I ran out of space because I changed the way I do offsite backups. > If all your directory trees lives in the same file system and that file > system gets filled up all bad stuff will happen at once. > > My own / partition is 510 MB and that also includes the /boot directory. > My biggest partition is /var/images at 101G where I keep some iso- and hd- > images I use with qemu. I think we all have to balance risks with the costs of management, and we will come up with different solutions based on our needs.
