HELP: change root mounting

[ua...@u.washington.edu]

i have a rz24 and rz56 in external storage and configured rz24 for rz1
and rz56 for rz0.
the root is mounted on rz1a and /usr is mounted on rz0g.

here's some congifuration i have..
rz1a as root
rz1b as swap/dump
rz1e as swap
rz1f as swap
rz0g as /usr
rz0h as /usr1

now i want to use rz0a as root file system..since rz0a is free on my system.
is there any way to change the config?
thank you

You'll have to modify the system configuration file. It's in
/usr/sys/conf/mips/SYSTEMNAME, where SYSTEMNAME is the name of your
system. Look for a line that reads something like

config vmunix root on rz1a swap on rz1b and rz1e and rz1f dumps on rz1b

Change that to move root. Build the new kernel. Now copy the old root
partition to the new area, and modify /etc/fstab on the new area to reflect
the new root disk. Make sure that you copy the new kernel into place on the
new root partition. Now boot the new kernel. If all goes well, it should
boot.

Good luck.
