+This will install a basic systemd setup in your initramfs, and is meant to
+replace the 'base', 'usr', 'udev' and 'resume' hooks. Other hooks with runtime
+components will need to be ported, and will not work as intended. You also may
+wish to still include the 'base' hook (before this hook) to ensure that a
+rescue shell exists on your initramfs.
