[Xen-devel] [OSSTEST v6 17/24] Debian: Handle lack of bootloader support in d-i on ARM.

[Ian Campbell <ian.campbell@xxxxxxxxxx>]

Debian doesn't currently know what bootloader to install in a Xen
guest on ARM. We install pv-grub-menu above which actually does what
we need, but the installer doesn't treat that as a "bootloader".

Most ARM platforms end up installing a u-boot boot.scr, based on a
platform whitelist. This doesn't seem appropriate for us. Grub is not
available for arm32. For arm64 we will eventually end up with in-guest
UEFI and therefore grub-efi and things will work normally. I'm not
sure what the answer is going to be for arm32.

This patch enables the workaround for Wheezy, Jessie and Sid,
post-Jessie should be enabled as we add them. (Pre-wheezy does not
support running as a Xen guest on ARM so we don't test them at all).
