Bug#614143: os-prober: generated linux entries don't use UUIDs for root= parameter
Package: os-prober
Version: 1.49ubuntu1
Followup-For: Bug #614143
Dear Maintainer,
Issuing update-grub command sometimes creates menu entries
for coexisting linux installations with
root=/dev/sdaX parameter at "linux" line.
My CentOS likes to name my drive at random "sda" or "sdb"
so entry mentioned above likes to cause CentOS boot to fail.
-------
I fixed my problem locally by applying following patch to:
/usr/lib/linux-boot-probes/mounted/90fallback.

After I rerun update-grub required entries were in place, i.e.
CentOS menu entry had root=UUID=xxxxx-xxxx-xxxxx-xxxxx parameter at "linux" line.
