Well, I recently asked the very same question in the redhat-devel question,
and got some great help.
When using initrd, the system boots as follows:
1) the boot loader loads the kernel and the initial RAM disk
2) the kernel converts initrd into a "normal" RAM disk and
frees the memory used by initrd
3) initrd is mounted read-write as root
4) /linuxrc is executed (this can be any valid executable, including
shell scripts; it is run with uid 0 and can do basically everything
init can do)
5) when linuxrc terminates, the "real" root file system is mounted
6) if a directory /initrd exists, the initrd is moved there
otherwise, initrd is unmounted
7) the usual boot sequence (e.g. invocation of /sbin/init) is performed
on the root file system
