[Vmdebootstrap-devel] Bug#805154: nobarrier option fails, needs more work

[Neil Williams]

mount() is used for all mount operations, including partitions with
filesystems which cannot support this option. So this change cannot be
done in the way described as it would disable all UEFI support and
other support required for systems which use a FAT partition for UBoot
or other bootloader/firmware needs. The change can only work for single
partition images or images where all partitions use ext? filesystems.
It needs to be constrained by the filesystem options.

command failed: ['mount', '-o', 'nobarrier', u'/dev/mapper/loop0p1',
'/tmp/tmpiEuwtc/boot/efi']

So the change would have to take into account the filesystem in use on
the relevant partition. For only a performance gain, it doesn't seem
worth spending that much time.

A patch would have to pass all the current slow build tests which
include a UEFI build.
