Upgrade to 9.0 - Mount to root failed..

[Airosoβicz fb.]

Greetings all,

It's my 1st time on any of the FreeBSD lists & I'm fairly new to FreeBSD to
please bear with me..

So I've upgraded from 8.1 to 9.0 & now the system can't mount in single
user mode to go through the final step of installing the world..

# cvsup.. Done..
# make buildworld..  Done..
# make buildkernel.. Done..
# make installkernel.. Done..
# reboot in single user mode to install world.. Failed to mount to
/dev/ad2s1a.. {Yes, that *is* my HD}

I rebooted from the loader prompt with my old (GENERIC) kernel & came up
with the following..

peggy# ls -l /dev/ad*
> crw-r-----  1 root  operator    0,  79 Apr  8 08:47 /dev/ad2

I know there's many 'mount' problem discussions out there but I can't seem
to find out how to overcome this problem..

Many thanx in advance for any assistance..
