Subject: [PATCH] Avoid installation of os-proper in VM environments

os-prober is known to cause problems in certain environments,
and might cause update-grub in the chroot to hang. The os-proper
package is a recommends of the grub-common package, so let's
install grub-pc by disabling recommends.

As reported on IRC by Paul Menzel.
