Mounts a filesystem of a given <fstype> on a <device> to a <mountpoint>. <device> can be one of /dev/ * or some arbitrary string if no device is needed for this driver (for example ramfs).
<fstype> is the filesystem driver to use. Try the 'devinfo' command for a list of available drivers.
<mountpoint> must be an empty directory descending directly from the root directory.
