I wasn't really asking about changing root after the system is up, the
part needed is the uncompressing of the filesystem into a ramdisk root f/s
or some such. After that it's pretty much open to any of several techniques.

Getting the modules loaded to support the root f/s and run a little rc
file to get things going is the bootstrap operation, and that's where
initrd is vital. You really don't want to build a kernel for every
machine if you have more than a few! One kernel and a few config and
initrd files is vastly easier.

What replaces the initial step?
