Partitions with a <mountpoint> specified will be automatically mounted.
This is achieved by wic adding entries to the fstab during image
generation. In order for a valid fstab to be generated one of the
--ondrive, --ondisk or --use-uuid partition options must be used for
each partition that specifies a mountpoint. Note that with --use-uuid
and non-root <mountpoint>, including swap, the mount program must
understand the PARTUUID syntax. This currently excludes the busybox
versions of these applications.

--use-label and --use-uuid are used at the same time,
we prefer the uuid because it is less likely to cause
name confliction. We don't support using this parameter
on the root partition since it requires an initramfs to
parse this value and we do not currently support that.
