Ah. The build process is not intended to create proper device nodes on
desk (non-root user can't do that); the image generation tools either
add the devices directly to the image or we use fakeroot to fake them.

You could mount a generated image file somewhere via the loopback
device. Then you would have the devices that are in the image. ext2
would be a good choice. Do you want to write back to the root or not?

Alternatively you could add a new target output format for NFS root.

Finally you could use something other than NFS root, if you don't need
to write back to it. Perhaps have your boot loader load a ramdisk via tftp.
