[Bug 1643614] [NEW] use grub-mount as the sole source of partition probes

[Obrouni]

Public bug reported:

Debian Bug has been fixed

https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=806273

Requesting for update to be applied and be available for Trusty and
Xenial.

os-prober makes partitions read only whilst it scans them, this can
cause corruption and loss of service in some uses cases. For example
Ceph OSD's are taken offline if journal write happens as same time as
os-probe. A Ceph cluster under heavy load will experience large numbers
of crashing OSD's if update-grub is run.

There are also reports of LVM volumes and KVM guests becoming corrupted
