_______________________________________________________
Details:
I have installed system using partitions:
ext4 /boot, LVM ( ext4-luks /, ext4-luks /home )
After calling update-grub I notice that the 'root' parameter in grub-cfg is
empty.
The reason is that grub-probe returns empty string if it tries to find a root
partition.
The grub-probe software checks whether device have name like "/dev/dm-X" by
checking their basename.
But device can have name like "/dev/mapper/dm-0-luks" and grub-probe skips
that device (which is root)
Fix attached as patchfile
