You have to adjust your /etc/fstab to reflect the change, if you don't, 
you will get a nasty looking error when booting (which can be worked 
out, I just don't remember if you have to tell you kernel on the boot 
console where your root is  or if you drop into single user mode and 
then have to "mount -o rw -u" your / to edit the fstab or both ;).
