I have a very similar situation, except in my case I need to
be able
to do local installs of software in /usr, thereby precluding
sharing
all of /usr.

Wow. Very interesting. But my 3.0-STABLE systems don't seem
to have
any magic symlinks and googling a bit doesn't give much
information
either. Is this integrated in -current (which I don't have a
system
running right now) or is hidden elsewhere?
Another option that I'm considering is whether I can do
anything
useful with union mounts to keep down the size of the images
for the
DomUs (i.e. mounting /usr via NFS from Dom0 and then
mounting a
smaller vnd on top of that).
Anyone tried that?
