[Bug 861884] [NEW] search for UUID fails, when grub is installed with grub-install

[wrigley]

Public bug reported:

running grub2 version 1.99~rc1-13ubuntu3.

imagine the setup:
harddisk: sda, usb: sdb

# mount /dev/sdb1 /mnt
# grub-install --root-directory=/mnt /dev/sdb
Installation finished. No error reported.

Trying to boot from the usb, grub fails: claims it can't find any drive
with the appropriate UUID. I have double checked the UUID with "blkid
/dev/sdb1", and it is correct.

if you don't have a spare usb to test on I have discovered the same
error when doing:

$ qemu-img create -f raw disk.img 80M
$ printf "x\nc\n1024\nr\nn\np\n1\n\n\na\n1\nw\n" |fdisk disk.img
# losetup /dev/loop0 disk.img
# losetup /dev/loop1 disk.img -o 32256
# mkdosfs /dev/loop1
# mount /dev/loop1 /mnt
# grub-install --root-directory=/mnt /dev/loop0
# sync
$ qemu -hda disk.img
