Thinking of a deployment trying minimize reflash times.

What if they have a signed Forth script to run on a USB stick that... ?

 - runs fs-update u:\myimage.zd -- a "small-sized" img
 - boots a signed kernel and signed initramfs from the USB stick --
where the initramfs just executes resize2fs, prints success/failure
and waits to be switched off
