block-mount fstab service causes unmount of all FSs
/etc/init.d/fstab restart causes all FSs to be unmounted and not mounted back. This is because it does not have reboot section so default one is provided. That one just calls
start in sequence. Problem is that
stop unmounts all FSs but
start just prints message that
fstab init script is obsoleted.
This is problematic because as part of update process we restart services. Restart of this service then causes just unmount of all additional FSs.
