[Bug 893614] [NEW] grub-probe fails if /dev/disk/by-uuid is missing

[Neil Wilson]

Public bug reported:

grub-probe can fail with 'grub-probe: error: cannot stat `/dev/disk/by-
uuid/xxxx`' if the mounted disk has had its UUID changed via 'tune2fs'.

tune2fs caused the /dev/disk/by-uuid directory to update and the old
link to be removed, but the entries in /proc/self/mountinfo have not
been updated.

This can cause fun and games when rebranding virtual machine disks
created from images.
