A question.

Why did you just not chroot under the mount point and then
just run passwd? I've always found that quicker and you don't have
to edit the shadow files, etc. As it does things in an orderly
fashion.

That's the problem with the Intel based hardware. In the
proprietary Unix environments many had firmware passwords, while
in the Intel environment you can often get to the BIOS and start
from there.

I vaguely recall on an AT&T 3B2-310 when that password was
forgotten you had to open the case, move a jumper, wait a few
seconds for the NVRAM to be cleared, put it bac, and then
re-assemble the case. And some of these had loops for locks
and/or security cables. So if someone goes through those you have
more than just a normal security problem - or there is a bit of
industrial espionage at hand.

So you ARE that masked man?
