+	  This can be either a single cpio archive with a .cpio suffix or a
+	  space-separated list of directories and files for building the
+	  initramfs image.  A cpio archive should contain a filesystem archive
+	  to be used as an initramfs image.  Directories should contain a
+	  filesystem layout to be included in the initramfs image.  Files
+	  should contain entries according to the format described by the
+	  "usr/gen_init_cpio" program in the kernel tree.
+
+	  When multiple directories and files are specified then the
+	  initramfs image will be the aggregate of all of them.
+
