If this is a -xen kernel, we should create a an initrd that can be used
by both dom0 and domU, i.e. it has the necessary hardware drivers, but
also the front end drivers.
 
Aren't there various differences between different distro's mkinitrd
routines? What distros will this script work on? [I recall that on
various FC versions (FC3?) its necessary to have an upgraded nash to be
able to build working initrd's at all]

It would be great to get a version of this script that's tested on a
bunch of different distros.

Thanks,
Ian
