Re: Minifridge

Never used cat and mv for editing.  No idea on that one. I'm kinda lost without vi. I did try to mount /usr and it blew  up. 'mount /usr' ended with a core dump and a reboot. I haven't yet tried bcheckrc because it's going to ask for a pass... And I ain't got one.  I did send a subscription to the list at ornl.gov, but haven't  heard back.

 You should be able to manage editing "/etc/passwd", etc. with `mv', 
`cat', etc. then. ;)

 OK, so that's definitely a Digital Unix of some flavour.  Try 
`/sbin/bcheckrc' as someone already suggested.  Note that ${PATH} is 
unlikely to include /sbin in the single-user mode shell which is less than 
useful -- I find it silly, but that's required for Bourne shell for some 
standard conformance I would guess.

 Yes, it is like this with DU -- the root filesystem (if separate -- 
that's what you need to check "/etc/fstab" for) is pretty minimal.  You 
need to get the system to mount /usr before you proceed.

 Note that if the system's got C2 security enabled then password 
information is managed in a database outside "/etc/passwd" and 
"/etc/shadow" and you'll have to poke at that database to get the root 
password reset.  After over 10 years I don't remember the details anymore 
and chances people here may not know them either as this is considerably 
away from how Linux does things.

 I suggest you check with a DU/Tru64 mailing list indeed or try system 
documentation available online.  It should be much better than the bits 
around the SRM console which I always found a little bit obscure and 
scattered around.

 Good luck!
