When $LUSER fills up his drive it can be that root is the only user that can properly mount and access the filesystem. So whatever the $LUSER was doing that filled up the drive needs to be undone by root, probably by shuffling stuff around. There are other cases where root might want some reserved space too, but fixing full drives is the only case I've ever encountered. -- Alan McKinnnon alan.mckin...@gmail.com
