The only one thing I ever ran into trouble with was device nodes,
these cannot be reproduced any way, not even with fakeroot
environments, just in scratchbox, which in turn needs you to be root.

initramfs etc can handle it with special description files. But if
you want to cook up say a .tar file of your rootfs, you're pretty
much lost AFAIK.

The good thing is that you don't need the device nodes
if you have udev, I think the kernel wants /dev/console
and a few more at boot but actually it survives just fine
without them.

The rest is possible to create with fakeroot and clever
scripting if I'm not mistaken.

If you know some way of sneaking a device node into a
.tar file created ENTIRELY running as a regular user,
tell me!
