My thing is memory resident, the kernel and root fs are all in one
file. That's not exactly hard to do.
Not quite what you're looking for though, as config (including passwd
Wouldn't be difficult to change though.
Having said that, I strongly recommend getting your stuff to the point
where it's a FAT formatted CF card, with a couple of files - 1 kernel,
1 filesystem image. Filesystem images are good.
That way, you can mount your CF card somewhere, and 'reflash' from a
live system. Just like, for example, a Cisco router. Upgrades are
easy, just copy a new root FS+kernel on there.
