Discover the Anatomy of initrd

IdaAshley writes "The Linux initial RAM disk (initrd) is a temporary root file system that is mounted during system boot to support the two-state boot process. It 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 this article explore the initial RAM disk for Linux 2.6, including its creation and use in the Linux kernel. In many embedded Linux systems, the initrd is the final root file system."

Options for fast booting by wall0159 · 2006-08-03 09:14 · Score: 5, Interesting

I don't know much about this, but am curious.

Why, once the system is booted cleanly, can't it save its state in initrd, and just load the state the next time without going through the boot process? Would that result in fast booting?
