Bug#741563: grub-mkconfig: uses_abstraction fails to identify rootfs on LVM

Package: grub-common
Version: 2.02~beta2-7
Severity: important
Dear Maintainer,
user story: I have my rootfs on a LVM volume, and after the latest
update of grub-common, grub-mkconfig no longer detects that, writes out
a "root=UUID=..." entry to grub.cfg, and this makes the boot process fail.
Bug analysis:
/usr/sbin/grub-probe --device /dev/mapper/vg0-root --target=abstraction | hd
00000000 6c 76 6d 20 0a |lvm .|
^^
Note the extra space. This makes the function uses_abstraction() in
grub-mkconfig_lib fail here:
317 abstraction="`"${grub_probe}" --device ${device} --target=abstraction`"
318 for module in ${abstraction}; do
319 if test "x${module}" = "x$2"; then
320 IFS="$old_ifs"
321 return 0
I guess grub-probe should be fixed not to output that extra space.
Thanks,
Nikolaus
