| 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. | |
