Public bug reported:

Using a DS that includes ec2 metadata with an ephemeral disk, even if
the ephemeral disk is not formatted with a filesystem, cc_mounts adds an
fstab entry that is likely invalid and potentially breaking reboot in
some cases.  I've seen this affect Debian based images and if needing to
reproduce, Rax OnMetal I/O flavor is a good candidate.  We are adjusting
the base images cloud config to avoid hitting this but, any other cloud
providers that provision non-formatted ephemeral disks would likely have
similar issues.
