Are we really talking about pygrub here, or pvgrub? (the former is
unaffected by mini-os).
If we are really talking about pygrub then we are _actually_ talking about
the domain builder when operating on the RHEL5 kernel+initrd -- the fact
ithat they were extracted from the guest filesystem by pygrub is
irrelevant.
