[ILUG] Root user

[Rafiq Maniar]

Hi Alvaro,

Can you boot into single user mode from the bootloader?

I haven't used Solaris for a while but Solaris10 seems to use grub,
first google hit is this:
http://www.cyberciti.biz/tips/solaris-boot-system-into-single-user-mode.html

That should dump you into a root login without ever having to use the
username 'root',
so hopefully that should work.

Alternatively, I'd suggest a rescue CD - it can't be too difficult to get a
USB cd drive.

As you said you can take the disk and put it into another machine, but I'd
be somewhat
wary about doing that when there are simpler means available. If the disk is
part of a
RAID set then its a definite no-no.
