	This may be a little overbasic, but these directions should be pretty
foolproof.  Make sure you're logged in as root --

	0: Are you satisfied with your system backup?  Good.

	1: Create directories called, for example, /newhome and /newusr.

	2: After creating the partitions on your new drive and mkfs'ing them, mount
the new partitions using "mount /dev/hdb1 /newhome" (substituting the
appropriate partion devfile and directory name)

	3: Copy the contents of /home and /usr to the new directories.  Use "cp -a
/usr/* /newusr/" to make sure directory trees and file attributes are
preserved.

	4: You'll probably want to eyeball the changes to make sure everything's
okay.  I think " diff `find /usr` `find /newusr`" may prove useful (those
are *backticks*, not single quotes!)

	5: When you're satisfied with the changes, unmount /newusr and /newhome,
and  edit /etc/fstab to reflect the new locations of /usr and /home.

	6: I believe "mount -o remount /usr" will then unmount the old /usr and
mount the new one.  Otherwise you'll have to do a manual mount and unmount.
Whichever works, do the same thing for your /home partition.


	Once this is done, you'll have new, presumably larger /home and /usr
partitions ready to go.  When you're satisfied that everything is still
working correctly (I'd give it at least a day or two, but I'm paranoid.),
you can clear out your *old* /usr and /home partitions and reuse the space
as /var or /usr/lib or something, or else use Partition Magic or somesuch
utility to delete the partitions and extend some other partition into the
unused space.
