Details:
using grub-2.00.5043-3 from arch linux testing.
grub-mkconfig line 131:
GRUB_DEVICE="`${grub_probe} --target=device /`"
on a btrfs raid GRUB_DEVICE now holds a list of devices. this fails in several
places when generating the grub.cfg.
for example the next line will fail:
GRUB_DEVICE_UUID="`${grub_probe} --device ${GRUB_DEVICE} --target=fs_uuid 2>
/dev/null`" || true
a solution would be to change this to:
GRUB_DEVICE_UUID="`${grub_probe} --target=fs_uuid / 2> /dev/null`" || true
and use GRUB_DEVICE_UUID instead of GRUB_DEVICE everywhere if set.
another quick fix would be:
GRUB_DEVICE="`${grub_probe} --target=device / | head -n 1`"
to only look at the first returned device.
