when testing precise alpha-1 I noticed some errors in the logs like this:

fsck: fsck.swap: not found
fsck: Error 2 while executing fsck.swap for /dev/xvda3
fsck.ext3: Device or resource busy while trying to open /dev/xvda2
Filesystem mounted or opened exclusively by another program?
..
mountall: fsck None [344] terminated with status 8

This was with cloud-config user-data like:
mounts:

• [ ephemeral0, /opt , auto, "defaults,noexec" ]
• [ swap, null ]

The resultant fstab had:
/dev/xvda2 /opt auto defaults,noexec,comment=cloudconfig 0 2
/dev/xvda3 None auto defaults,nobootwait,comment=cloudconfig 0 2

There should not be an entry for swap.
