I have installed netbsd on a sun Sparc Station Classic.

The only problem is... I CAN'T FREAK'N MOUNT THE ROOT DIRECTORY READ/WRITE
TO CHANGE A FILE INT /etc!!!!

here's what I get when I boot into the system:

# /sbin/mount -u -w /
mount_ffs: /dev/sd0a on /: specified device does not match mounted device

to start, here's a bit of dmesg:

Here's fstab:

/dev/sd0a / ffs rw 1 1
/dev/sd0b none swap sw 0 0
/dev/sd0g /usr ffs rw 1 2

Here's what 'mount' gives me right now:

# mount
root_device on / type ffs (read-only, local)
/dev/sd0g on /usr type ffs (local)

# mount -u -w /dev/sd0a /mnt
mount_ffs: /dev/sd0a on /mnt: specified device does not match mounted
device
# mount /dev/sd0a /mnt
# vi /mnt/etc/rc.conf

ex/vi: Modifications not recoverable if the session fails
ex/vi: Error: /mnt/etc/rc.conf: Read-only file system

# mount
root_device on / type ffs (read-only, local)
/dev/sd0g on /usr type ffs (local)
/dev/sd0a on /mnt type ffs (local)

Ok, so I figure I should boot up the install system (which is on an
external scsi-disk) and change it from there:

ok probe-scsi

Since then (this project has been on hold for a month or so because of
this hang-up) I've tried mounting part of that external hd onto /var/tmp
so that I could use vi, and I've also tried installing the system with
both the new and old procedures, as well as choosing different
combinations of sets
(currently everything's on there :(

Can anybody help me out here?  I would really like to get this system up
an running so I can play ;)

Any help would be greatly appreciated
