No specific example. Last couple of times I have just done the console
thing. Only other time I had a problem someone else added a user and
changed the word 'root' in /etc/shadow to 'Root' (you know, down arrow
or something changes the case of letters sometimes in vi on Solaris).
That one nothing would fix short of a CDROM boot. (Actually didn't have
a CDROM drive since someone hid it on me. Had to take the damn drive
out, put it in another box, run devfsadm to get it recognized, mount the
partition and edit the shadow file.)

We now have a console server so I can get to the console and aviod stuff

I'd rather not have anyone logging in directly as root on the boxes I
admin. In fact, I think the "rules" may forbid that expressly.

Only thing I have done is write on the calendar the next time we need to
change the root password. I guess you could set up a cron to email you
once every password-change-period or something like that. Maybe I'll
look into that: an email when the password expiration is 10 days away or
Ought to be able to compare the third field in /etc/shadow (last change
in days since the epoch) with today's date in the same format and send
an alert if it is greater than a certain number.
