Do an 'fsck' on the root partition, to make sure that any garbage left
from the unscheduled power-down is cleaned up. I believe that you
won't be allowed to mount it otherwise; but why take chances?

Do NOT mount it to /tmp. Too many things write to /tmp without telling
you. Mount it to /mnt, or some other directory that is otherwise
unused. If there is no unused directory on the file system, and you
can't create one, then find a directory that only contains stuff needed
to install SunOS/Solaris (which you aren't going to be doing), and
mount it there.

I would get a "known" password, rather than just removing the password.
But I'm notoriously paranoid about these things.
If you have shadow passwords turned on, change the shadow password
file, rather than the /etc/passwd file.
Do NOT replace the current file(s) with old versions; other users may
have made changes. Only change the passwd field of the appropriate
file.
Once you have changed the file system, remember to 'sync' and unmount
the file system; otherwise, your file system state may not be clean,
and you will have to 'fsck' and possibly do this all over again.
