The behavior is the same in 8.2. Instead of disabling UUCP locking,
what do we have to do to make it work correctly? Maybe create the dir
and use setuid or setgid?

I suspect the problem here is that either you or root or both have a
~/.kermrc that has some configurations left over from when rar.mit.edu
was a DECstation.

For the DECstation mkserv modem would enable this. Unfortunately
that's never been set up for the sun. However I have set up somethign
like this on one of my suns, so I can tell you how I did that. I
added a line that looks a lot like the foolowing to /etc/inittab:
sa:234:respawn:/usr/lib/saf/ttymon -g -h -p "\\n\\nMIT Athena on `uname -n` (`uname -rs`)\\n\\nlogin: " -T vt100 -d /dev/term/a -l console -m ldterm,ttcompat
The only problem with this is that version updates will remove this
change. To get around that problem, I added something like the
following to /ver/server/.private (with is a script that mkserv runs
whenever it is invoked):
(grep "^sa" /etc/inittab >> /dev/null || \
echo 'sa:234:respawn:/usr/lib/saf/ttymon -g -h -p "\\n\\nMIT Athena on `uname -n` (`uname -rs`)\\n\\nlogin: " -T vt100 -d /dev/term/a -l console -m ldterm,ttcompat' >> /etc/inittab )
