[Pkg-xen-devel] Bug#685749: xen-utils-4.1: /usr/lib/xen-default missing

[Oliver]

Subject: xen-utils-4.1: /usr/lib/xen-default missing
Package: xen-utils-4.1
Version: 4.1.3-1
Severity: important

Dear Maintainer,

when using paravirtualization with xen and libvirt the path for pygrub is:
/usr/lib/xen-default/bin/pygrub

But this path is not provided with xen-utils-4.1 and will brake upgrades to
wheezy.

With xen-utils-4.0 and debian squeeze this path is provided with
update-alternatives in the postinst Skript.

With xen-utils-4.1 the alternative command in the postinst script removes
xen-default. Why?

This patch fixes the problem:
