It seems you are using devfs; try running without it. I don't see
much advantages of devfs for embedded systems where such a
flexibility is usually not needed, on contrary.
Well, I see at least two advantages: a) you don't need to have root
privileges to assemble your root-filesystem, b) it's the way /dev
should have been implemented in the first place.
I admid both arguments cover rather aesthetical aspects, so your
mileage may vary.
The main disadvantage is the increased memory footprint which you
have to pay for a flexibility on the target which is usually not
necessary.
Your (a) is not really an argument; there are several solutions for
this "problem", for example:
genext2fs - ext2 filesystem generator for embedded systems
see http://packages.debian.org/unstable/admin/genext2fs.html
gBootRoot - distribution creation program which may be used by a normal user
see http://gbootroot.sourceforge.net/
(b) is a matter of taste; for embedded systems, I tend to prefer a
fixed, static configuration which does not cost too much of the
resources which may be somewhat limited (espacially ROM and RAM).
Yes, MMV ;-)

By the way, ALL software projects are done by iterative prototyping.
Some companies call their prototypes "releases", that's all.

I've made a patch for e2fsprogs that makes it possible
to use debugfs to create ext2-images from userspace.
If that program is used together with fakeroot
it's possible to do everything* without root access.
*if everything is generating your target filesystem with
correct permissions and uids/gids
I think that is nice.
Mail me if you want the patch.
