Does this not have some benefits? IE: I can restrict how large the log
files can grow, etc? 

Since I'm now stuck with having /home as part of the main filesystem, from
what I have read the best option is to apply a quota to the group of
users I'm interested in (IE: the group "students" for example).  And, if I
understand that correctly, what I am doing is specifying a quota size that
the *whole* group cannot exceed, rather than specifying a quota which the
system will then apply to each member in the group. Is that correct, or
did I just give everyone a 1 gig quota?

Thanks,
Joseph
