You cannot really call this a "minimal root filesystem".

A small (not even this is minimal, nor optimized) image can be found at
ftp://ftp.denx.de/pub/LinuxPPC/usr/src/mini-2048kB-ramdisk.image.gz

This has:
	-> find .
	.
	./lost+found
	./bin
	./bin/sh
	./bin/ls
	./dev
	./dev/ttyS0
	./dev/tty
	./dev/console
	./lib
	./lib/ld.so.1
	./lib/libc-1.99.so
	./lib/libc.so.6
	./lib/libtermcap.so.2.0.8
	./lib/libtermcap.so.2
	-> du -sk .
	1367    .

Obvious optimizations: rmdir lost+found, use busybox instead of  bash
+ ls, ...
