Unconfined filesystems created through CLI in HNAS caused driver's
parser to break. It was found that the command breaking could be
replaced by another, already used command, which also retrieves
filesystem information, and it is preferred, so previous command
has been replaced.
Additionally, administrator may not want to automatically mount
an unmounted filesystem in DHSS=False mode, which may be unmounted
for maintenance, so changed behavior to not mount automatically.
