Comment 1 for bug 744019

The reason that cloud-init wrote that entry in /etc/fstab is that the metadata service on t1.micro includes 'ephemeral0', even though there is no ephemeral0.

I'm fixing this by:
a.) special casing "ephemeral0" and device does not exist
b.) changing the warning on swap conversion to a debug statement (so it wont go to console)
