Agree with the second.  On the first we differ in that quot can take a long
time, as opposed to "quota user" which just reads a precomputed file for you.
The quota hacks in the kernel aren't near as slow as the quotacheck on boot,
so your way is still well worth considering!  The nice thing about having
quota turned on is you can _do_ something about the numbers you see -- depending
on how big your disk farm is and how many users you have, there are going to
be tradeoffs.  Whether you want your users to take the action or whether you
expect it to be your job to remove files is part of that trade-off.

(Gee whiz, how did you get manuals?  They won't buy us any here, they claim
UNIX is trivially obvious and everything can be intuited with a little effort.)
