Linux initrd (initial RAM disk) overview
Initrd is one of those things in linux which most of us have taken for granted. Here is a very interesting writeup on how initrd really works. "The LinuxÃ‚Â® initial RAM disk (initrd) is a temporary root file system that is mounted during system boot to support the two-state boot process. The initrd contains various executables and drivers that permit the real root file system to be mounted, after which the initrd RAM disk is unmounted and its memory freed. In many embedded Linux systems, the initrd is the final root file system. This article explores the initial RAM disk for Linux 2.6, including its creation and use in the Linux kernel."
