See: 
http://www.kernel.org/pub/linux/kernel/people/gregkh/lkn/lkn_pdf/ch09.pdf

in particular rdinit=... for ram disks.

linuxrc is the first thing that the kernel looks for (instead of init). 
It could also be a shell script. You might want to look over at 
linuxfromscratch.

http://www.linuxfromscratch.org/

Nothing to say that linuxrc is just a shell script with an exec /bin/sh 
in it (or something like while (true); do /bin/sh; done)

Jason.
