The default value is 16 RAM disks. Change this if you know what

- 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.

- See <file:Documentation/early-userspace/README for more details.
+ The default value is 1024 bytes. PAGE_SIZE is a much more
