/remote/laptop is mounted over NFS. /remote/laptop is the / of my laptop and it
is physically on the laptop. The desktop is compiling and hopefully, using
"ROOT=/remote/laptop" is emerging the software remotely to the laptop.

I don't have /remote/laptop always mounted (only when the laptop is powered on
and I want to emerge packages there), and I'd need to do the mount -o bind
commands after I mount /remote/laptop. I agree that this is not much of an
issue. A proper shell script would do the mounts right when I need them.

There is still the problem of using the slow disk of the laptop (for all
headers, libraries, etc. while compiling) over NFS, if I chroot to
/remote/laptop.
