# Create an initial ramdisk containing the closure of the specified

# file system objects. An initial ramdisk is used during the initial
|

# stages of booting a Linux system. It is loaded by the boot loader
|
||||
# along with the kernel image. It's supposed to contain everything
|
||||
# (such as kernel modules) necessary to allow us to mount the root
|

# file system. Once the root file system is mounted, the `real' boot
|

# script can be called.
