[Xen-devel] [PATCH OSSTEST v2 07/19] Enable chain loading to local disk for UEFI PXE systems.

[Ian Campbell <ian.campbell@xxxxxxxxxx>]

First arrange for bootloader to be installed to removable media path,
by using a new in Jessie preseed option. Then use that to chainload a
bootloader from the disk.

The removable media path is well known (part of the UEFI spec) which
saves us having to worry about which OS is on the host (so long as the
OS can be configured to populate the removable media path)
