[Bug 1501015] Re: ISST-LTE: Multipath disk is not automatically set as 1st boot device after installation

[Mathieu Trudel-Lapierre]

Does this bug also happen at all on 14.04?

This bug report mentions "The symptom is the same as launchpad bug
1486022 against 14.04.3.", yet it also mentions this is for installs of
15.10.

I've already created the tasks for 14.04 and 15.04, but there is no
point in doing stable updates and risking to introduce new issues from a
rebuild or a new version if the bug isn't happening on these releases.

Bug description:
  == Comment: #11 - Gary M. Gaydos <gmgaydos at us.ibm.com> - 2015-09-29 14:37:05 ==
  Steps to reproduce:

  Install 15.10 beta 1 ppc little endian using multipath disks (in this case mpatha)
  After the installation is finished no device is set as the first boot device.

  The symptom is the same as launchpad bug 1486022 against 14.04.3.
  Syslog from 1486022 and this bug are different however.  In 1486022 no
  mpath devices are found.  In this bug mpath2a (the installation
  target) has an unknown device type, and the volume group is not found.

  Here's a snippet from the syslog

  cat syslog |grep -a2 -b2 mpatha2
