ulimit (was: getty/login for callba

[flint at gistdev.UUCP]

In several years of real world running of systems, looking at the
systems that many of our clients have been running, etc., I've only
seen the ulimit do any good in one case, and that is to keep /etc/utmp
from filling up the root partition on a system that doesn't get
watched much.  However, I've seen numerous cases where the ulimit got
in the way of doing real work.  (If you want a useful parameter put in
one that says how many entries to keep in utmp.)
