Ah, I just run everything as root. Much easier ;-)

What I'm after is more along the lines of your, with the
image creation a separate step. If the chain gets complicated,
then a Makefile can take care of it.

mkjffs2 is easy. Things are more complicated for mkext2 and mksd
since they use loopback mounts, which fakeroot doesn't emulate. I
haven't found anything that has the reverse function of debugfs'
rdump yet, but if all else fails, just doing this as root and
simply dumping the tar won't be so bad either.

Your rootfs builder looks really good !
