look at populate_rootfs(), it's that simple. Our local kernel tree has
the following in the boot/simple/Makefile:
ZRDIMAGE := $(images)/ramdisk.image.gz
ROOTDIR := $(srctree)/............/path/to/dir/containing/root-fs
$(ZRDIMAGE) : $(OUR_LOCAL_RULES_FOR_BUSYBOX) FORCE
(cd $(ROOTDIR) && find | grep -v '~$$' | cpio -o -Hnewc ) | \
gzip -9 -c > $@
