+This hook allows for an encrypted root device with systemd initramfs.
+
+See the manpage of systemd-cryptsetup-generator(8) for available kernel
+command line options. Alternatively, if the file /etc/crypttab.initramfs
+exists, it will be added to the initramfs as /etc/crypttab. See the
+crypttab(5) manpage for more information on crypttab syntax.
