Last time I did this, it worked fine ... just make sure the "slices" (right term?)
correspond with your /etc/fstab, or you'll end up in single user or even
stuck at a boot prompt with the new drive the first time out.

I'd recommend dump and restore ... possibly piping dump *to* restore,
something like:

dump -0 -a -L -u -f - /usr | ( cd /newusr ; restore -ruf - )
