-	  Build a file which is usable for the gen_init_cpio tool
-	  at linux kernel build.
-	  This file is normally called initramfs_list and can be
-	  generated with gen_initramfs_list.sh script from the root
-	  directory structure.
-	  The file is then used in the kernel build process to generate
-	  the cpio filesystem for the initial ramdisk. Make sure that
-	  you configure this file in kernel build configuration.
-	  The location in the kernel build configuration menu is
-	  Device Drivers -> Block devices -> Initramfs source file(s).
-	  The configuration variable is CONFIG_INITRAMFS_SOURCE
+	  Integrate the root filesystem generated by Buildroot as an
+	  initramfs inside the kernel image. This integration will
+	  take place automatically.
+
+	  The rootfs.initramfs file generated in the images/ directory
+	  is only a text file describing the contents of the initramfs
+	  in a format understood by the CONFIG_INITRAMFS_SOURCE kernel
+	  configuration option.
+
+	  Note that enabling initramfs together with other filesystem
+	  formats doesn't make sense: you would end up having two
+	  identical root filesystems, one embedded inside the kernel
+	  image, and one separatly.
