hmm, IIRC, the purpose of fstab.remote was to have something
which is done from withing the guest's network namespace,
so I would assume that it already uses the guest IPs, but
maybe daniel can clarify here ...
anyway, you might want to use one of the pre-pre scripts and
limit your networking to the guest ip you want to do the mount
from (with chbind)
