Couple of things.

Firstly, why use a gentoo live disk? Just log in as root.

Secondly, why rename home? Just mount sda5 on /mnt to do the move, then 
add it to fstab to mount on /home.

And a little bit you might have missed - DON'T put root's home on a 
mounted disk - if it's currently in /home, move it to /. Don't forget to 
edit /etc/passwd if you have to move it.

The other way to do it is if you've got a spare hard drive lying around. 
Just copy /home onto it (bearing in mind my comment about root's home), 
and then copy it back.

But what do you mean by "save drive"? Just splitting the drive into 2 
partitions won't do anything, will it? If you want to "save the drive" I 
think you need to move /home to spinning rust :-) Unless you're 
physically updating the hardware, I wouldn't bother.
