systemd-system-update-generator – Generator for redirecting boot to offline update mode Synopsis /lib/systemd/system-generators/systemd-system-update-generator Description systemd-system-update-generator is a generator that automatically redirects the boot process to system-update.target, if /system-update exists. This is required to implement the logic explained in the systemd.offline-updates(7). systemd-system-update-generator implements systemd.generator(7). See Also systemd(1), systemd.special(7)

systemd-sysext, systemd-sysext.service – Activates System Extension Images Synopsis systemd-sysext [OPTIONS…] systemd-sysext.service Description systemd-sysext activates/deactivates system extension images.
