You may not have to go that far.  I successfully moved several
directories out of /usr with no ill effects.  I had some spare
space in another partition and did the following:

cp -a /usr/src /admin
cp -a /usr/doc /admin
rm -rf /usr/src
rm -rf /usr/doc
ln -s /admin/doc /usr/doc
ln -s /admin/src /usr/src

Now I have lots of space in /usr, plenty of space to compile
kernels and the nearly useless /doc directory put somewhere
more appropriate.  (When they have all of the docs and manpages
html'ized and cross-linked, they'll be useful again.  I'm used
to this from AIX and I guess I'm spoiled...)

If you need to do something more drastic, you'll have to
reboot, at least.  Disks are cheap nowadays, I'll probably
give /usr 2GB from now on.  Back when I partitioned some of
these boxes, 800MB for /usr was overkill...

Caveat:  Make sure that /usr is in the same mount group as
where the files are moving to, preferrably mounted afterwards.

Just my 2 cents.
