Ben reported that distro GRUB may fail to boot in some circumstances,
and tracked it down to an issue in the way distro GRUB allocates space
for the image. Due to an oversight (addressed in patch #2), this
condition is rarely triggered, but let's work around it in any case (#1)

Remaining patches add further warnings for conditions that are unlikely
to occur, but should not be ignored.

Build tested only.
