Test systemd-generators
    
    Display some basic system information and list generators which are
    confined and which are not, then run particular tests with some
    adjustments for:
    - systemd-network-generator
    - systemd-fstab-generator
    - systemd-rc-local-generator
    - systemd-sysv-generator
    - selinux-autorelabel-generator
    and finally run again all generators with default settings as an effect
    of "systemctl daemon-reload".
