This is certainly not true here. I have fifteen or so accounts set up
for uucico login - all with different UIDs. However, they each share the
uucp (ie. mail) group ID. Since uucico doesn't run setgid, this doesn't
seem to matter one way or the other.
Possibly someone with source could take a look and see just what sequence
of events occur when a uucico session starts up. I would be interested in
being enlightened further.
