David,

pdisk and parted are packages seperate from bash and the kernel. I believe
parted is installed in a default install, but pdisk will have to be installed
from the CD. Mount the CD and look for a RPM like pdisk-0.8-2.ppc.rpm. Then
do a 'rpm -ivh pdisk-0.8-2.ppc.rpm' to get it installed.

The entry you put in /etc/mtab should go into /etc/fstab instead. /etc/mtab
is a "system file" that maintains a list of currently mounted filesystems.
Once you reboot, the file is re-initialized.

Once you reboot, and /home is set to /dev/hdb12, your original /home partition
and it's data won't be available to you. You have two options, maybe more, to
move your data. 1) move your data to a partition that won't get unmounted on
reboot; or 2) create a new mount point and mount the original partition there.
If I were doing it, #2 would be the "best" way. Remember, your data will
always be on that partition until you do something destructive to that
partition; over-write or delete files or re-initialize.

When you reboot, switch user to root:
  [ken@byte-8 ken]$ su -
  Password:
  [root@byte-8 /root]#

Create your new mount point:
  [root@byte-8 /root]# mkdir /mnt/oldhome

Mount your old home partition:
  [root@byte-8 /root]# mount -t ext2 /dev/hdaX /mnt/oldhome

Verify you have oldhome and home mounted (both should be listed):
  [root@byte-8 /root]# mount

Copy your data to the new home:
  [root@byte-8 /root]# cp -a /mnt/oldhome /home

Verify your data copied. If so, unmount oldhome:
  [root@byte-8 /root]# umount /mnt/oldhome

Enjoy your new home partition.
