darkstar:~# mkinitrd --help
mkinitrd creates an initial ramdisk (actually an initramfs cpio+gzip
archive) used to load kernel modules that are needed to mount the
root filesystem, or other modules that might be needed before the
root filesystem is available. Other binaries may be added to the
initrd, and the script is easy to modify. Be creative. :-)
