Sorry for getting back to this slowly.
I didn't really follow you above.

The 'cloud-config-mounts' will go away if you're using something later
than 10.04, so I'd try not to rely on that.

If you want to post more details of what you did, i can look at it and see
if it seems sane.  I will have an interest in seeing the same thing
functional on precise also.
