David,
I doubt there's much you're going to be able to do other than reset the
password. 'pjones' doesn't look like a valid password hash of any kind
so I can't think of a way to crack it even if you wanted to do something
like that. Of course I will bow to anybody who has superior
forgot root password
Are you able to login to Single User Mode? On a vanilla installation it
doesn't ask for the root password, so you should be able to mount the
system and run chpass again.
Regards,
Russell Wood
