[Bug 1416396] Re: Unknown file system warning messages during dist-upgrade operation

This isn't a grub2 bug, but an issue caused by the way os-prober does
the filesystem probing to display other installs in the grub menu. I'm
setting both the grub2 and os-prober tasks to "Won't Fix": if we really
want to make these messages disappear, the changes will not happen in
os-prober or grub2.
The ideal solution to this is to deactivate os-prober on the system;
otherwise a lot of effort may be needed to reduce the severity of the
messages (although they are relevant, and certainly meaningful, if
someone goes to mount a filesystem with the wrong type). To figure out
whether another install exists on the disks, os-prober needs to do some
probing and mounting of the filesystems (we can't use only the partition
table to guess the filesystem) to see if there are kernels, or
configuration files, it understands and to read them to know what the
other operating system is.
My recommendation is to set GRUB_DISABLE_OS_PROBER=true in
/etc/default/grub to disable probing if no other operating systems are
installed on this system; then no probing will happen on upgrades, so no
messages will show up on the console.
** Changed in: grub2 (Ubuntu)
Status: Confirmed => Won't Fix
** Changed in: os-prober (Ubuntu)
Status: New => Won't Fix

---Problem Description---
LVM & Unknown file system related warning messages during dist-upgrade operation
Contact Information = Sachin Sant / ssant at in.ibm.com
---uname output---
3.18.0-11-generic
Machine Type = POWER8
---Debugger---
A debugger is not configured
---Steps to Reproduce---
1) Install Ubuntu 15.04 as a Power VM guest. I have used LVM based partition scheme during installation.
2) Post installation execute following commands :
apt-get update
apt-get dist-upgrade
While installing kernel package following warnings are displayed
