We should add more specific control by adding mount options.
Just like NFS mounts can be done in the background, so can
we have a mount option that doesn't cause a fail when the
underlying device isn't there, but instead results in mount
blocking until the device arrives. This then can be combined
with a background option to have the boot continue while the
mount is pending.
