why not all of /opt?  I guess I'm a little surprised that when people 
say "diskless", they actually mean "root is tmpfs/ramfs".  we run diskless,
but simply use NFS root.  (lots of benefits from having root be a single 
filesystem, since updates become not worth mentioning...)

I'm going to play dumb here, but what's gamey about symlinks?
(I'd probably just use a mount or bind-mount, but same effect.)
