How do you deal with space crunches caused by root daemons? I'm thinking
specifically of one which I usually end up finding and fixing on older ECE
machines: /{usr,var}/vice/cache fills up the filesystem it's on and both
the AFS client and the system start doing weird things. Nowadays we give
/var/vice/cache its own partition so the system doesn't go insane when AFS
oversteps its cache limits. (And even if a quota could be applied, its main
effect would likely be to confuse the AFS client even more. It's not very
smart about caching....)
Also, there's the question of quota overcommit: even with restrictive
quotas, one might still run out of disk space if the quotas add up to more
space than is available. Keeping track of that can be an administrative
nightmare even with decent tools.
Quotas are a possible answer for some situations, but not for all of them.
