I apologize to interrupt your conversation :-)
but unless I've misread the documentation, the quota feature
is pretty useless IMHO, at least in AIX 5.2.
Of course mileages may vary, but the most common application I can imagine
would be to limit all users of group to a certain amount of disk space
*by default*, but allow a bit more for a few "power users".
sth like
edquota -g people 4GB
eqquota -u diskhog 40GB
This isn't possible, AFAIK, the whole quota system is very clumsy to use.
