9 | This can be either a single cpio archive with a .cpio suffix or a |
10 | space-separated list of directories and files for building the |
11 | initramfs image. A cpio archive should contain a filesystem archive |
12 | to be used as an initramfs image. Directories should contain a |
13 | filesystem layout to be included in the initramfs image. Files |
14 | should contain entries according to the format described by the |
15 | "usr/gen_init_cpio" program in the kernel tree. |
16 | |
17 | When multiple directories and files are specified then the |
18 | initramfs image will be the aggregate of all of them. |
