[ubuntu-cloud] Refreshed Cloud Images of 12.04.1 LTS (Precise Pangolin) [20121001]

Mon Oct 29 17:57:15 UTC 2012

I know this is an old post (to which I respond) but is this related to the 
upgrade error messages I'm seeing:

/usr/sbin/grub-probe: warn: disk does not exist, so falling back to 
partition device /dev/xvda1

I've seen this on 11.10 and 12.4 AMD64.

If so, it appears the correct location for this edit is actually 
/etc/default/grub on the AMI (at least for 11.10).

But, my problem seems to be the location of the boot device. It seems 
upgrading grub creates issues with mounting the /dev/xvda1 location 
specified. I'm assuming grub is failing to see the pount point and prefers 
something like /dev/sda1, though admittedly I haven't spent much time 
narrowing the challenge. This appears to be a failure on AMIs for both 
11.10 and 12.4 AMD64, perhaps others.
