Since you can run Qemu as a non-root user, and you can present an
arbitrary file to it as a disk, it seems that you should be able to
use the standard disk tools within a Qemu guest to do what you want.


Thanks Dale.  I was hoping I could do something like this.  I'll explore that further.

Tony, I am wanting to run as non-root because it is my Jenkins build-server that will be doing all of this which needs to run as non-root for security sake.  I want the last stage of my build to produce a uSD card image.
