Restoring system settings expects a filename of 14 characters followed
by .tar ($DATESTAMP.tar from the backup file the addon creates).
Change to glob onto whatever *.tar file gets put into /storage/.restore/
at the busybox init and system restore level. The addon still creates
and expects the $DATESTAMP.tar file, so users will need to use this
feature by ssh or other method.
