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.
