[A lot of stuff deleted, but not forgotten]
I've restated the problem in the form of a question below. You've mentioned,
"Another FAQ question?" Maybe you're right, so I'll deal with it that way and
maybe the FAQ maintainer will consider it.

Note that the symlink idea wasn't what you wanted -- completely forget it.
Here ya go:
Q: My root filesystem is getting kinda full. I've install another disk and I want to move my /home or /usr directory onto this new disk. How do I do it.
A: Let's assume that new disk is called "/dev/hda3" and you've decided to move the /home directory to this new disk. The steps are as follows:
First, make a temporary place to mount the new disk.
0) mkdir /home1
1) mount /dev/hda3 /home1
Now, copy all of the stuff in /home to /home1
2) ( cd /home ; tar -cf - . ) | ( cd /home1 ; tar -xvpf - )
I sometimes do a recursive diff of the directories for extreme safety. This really isn't necessary, but sometimes I'm paranoid. Also, if you have a really big file in /home somewhere, diff will die of memory exhaustion.
3) diff -r /home /home1
Number "3)" should report nothing at all.
Again, for extreme safety, do
4) mv /home /home2
That will keep "/home" around for just a little, until you're real happy.
5) mkdir /home
6) unmount /dev/hda3
7) mount /dev/hda3 /home
8) give /home the same permissions and ownership that /home had before.
9) emacs /etc/fstab # or what ever editor you like
Make sure you have a line in there that does
/dev/hda3 /home ext2 defaults 0 0
10) Reboot
11) Check things out. Make sure you log in as a normal user.
Now you're real happy.
12) rm -fr /home2
13) rmdir /home1
