Bug#456776: grub: Please support installation Xen virtual block devices

[Ian Campbell]

Package: grub
Version: 0.97-29
Severity: normal
Tags: patch

The grub package does not currently support installation in a Xen
guest domain because it does not understand the Xen virtual block devices
(/dev/xvd[a-z]).

This support is mainly useful because it allows the Debian installer to
work in a Xen guest without Xen specific workarounds.

It might also be useful for someone who wanted to switch between
a guest between para-virtual and fully-virtualised (HVM) operation.

Patches for grub-install and grub itself (for device.map generation) are
attached.

Thanks,
Ian.
