Pkg xen devel - Nov 2012 - Bug#588839: Include pv-grub to securely boot guest kernels

How exactly would the existing packages be re-used ?

The resulting binary of PV Grub will not be run on the Dom0, it is
cross compiled to run as a stub domain under the hypervisor directly
and it will not have access to the dom0 at that point so I don't see
how you'd re-use the packages installed on the dom0.

Cheers,
