Bug#755256: grub-xen: Cannot boot XZ compressed kernels

Package: grub-xen
Version: 2.02~beta2-10
Severity: important
Dear Maintainer,
Currently grub-xen cannot boot kernels which are configured with
CONFIG_KERNEL_XZ=y and reports "error: not xen image.". The Debian
kernels have been compiled with this option since
3.6.8-1~experimental.1.
Fixing this is as simple as adding an "insmod xzio" after the existing
"insmod gzio" in /etc/grub.d/10_linux. ("insmod gzio" needs to stay for
compat with Wheezy kernels)
It is possible to extract the compressed payload from an x86 bzImage and
inspect the magic numbers to determine the required decompression
algorithm, but that seems like a lot more work for a pretty small gain.
Cheers,
Ian.
