I just had something really unusual happen to me while running NetBSD-1.0.

All at once, all my logins started appearing as "root." In other words, when
you logged in on any account, the system would attach you to the appropriate
account directory, but then I'd get a Warning from SH about having a dot in
the Path, then the prompt would come up with root@machine. I would also get
a response of root from whoami.

Has anyone seen this before?

I ended up fixing the problem in an equally strange way. I booted up off of
the UPGR-10.fs floppy and let it do it's install thing. I had noticed before
that it copies a new .profile to / and rename's /etc/rc to rc.bak, as well as
I'm sure, many other things, like tweaking with the passwd file. This seemed
to re-sync things with the logins.
