[Bug 1431743] Re: fails to boot with broken or missing root fs fstab entry

[ibob63]

I agree with ironstorm.  This bug clearly needs to be reopened.

I just upgraded my server and it became read only.  I can confirm that
the problem for me was that after upgrade the fstab had the wrong UUID
in it.  Bizarrely, it was changed from:

UUID=18254707-08e8-494e-b456-938592928a5e / ext4 errors=remount-ro 0 1

to:

UUID=815063a9-c956-44a6-ab11-05e1d0bb3a58 / ext4 errors=remount-ro 0 1

The server was virtual and luckily I took a backup before upgrading.  I
therefore restored the backup, upgraded again and then dropped into the
command prompt and corrected the fstab before rebooting the server.

As Ironstorm suggests, this should be a post install check or perhaps
the bug which is causing this issue can be resolved.  I'm sure that this
issue will affect lots of other people and it should be reopened as an
issue.
