*** Know issues

** (1) On shutdown lots of messages from systemd like:

    "Could not unmount /run/parabolaiso/<ABC>: Device or resource busy"
    "Could not delete loopback /dev/loop<N>: Device or resource busy"
    This is not a real issue since, all mounted filesystem, loopback devices
    and device mapper devices made by parabolaiso will be "free" on "shutdown tmpfs"
    (A.K.A deinitramfs), build at initramfs by [parabolaiso_shutdown] initcpio hook.
    Proper shutdown is mostly important when persistent is used.
