I didn't specify the environment entirely. The laptop has a small hard disk and
it has only /, /boot and a swap. The "/" is mounted over NFS on the desktop. I
want to be able to do (on the desktop)

ROOT=/remote/laptop emerge vim

and have vim on my laptop. However, if I chroot to /remote/laptop, I'd end up
making all communication over NFS and using the hard disk of the laptop for
compiling as well, which is not very fast. I was doing something with

mount -o bind /var/tmp/portage/ /remote/laptop/var/tmp/portage/

which speeds up things a bit, but it is still slower and too annoying to do
every time.
