/sbin/init and /bin/sh are not statically linked, so you won't be able to 
run these from your memory disk.

Take a look at src/distrib/i386/ramdisks/ramdisk-big to see how the 
install memory disk is made with crunchgen. You should be able to easily 
adjust the Makefile and list files to build your own.
