I probably got it wrong.
but it seems the programs purpose is to build images (boot loaders). I
then wonder why it needs to do this during installation. If image
building is the programs purpose, it should happen during execution
after installation, no ?
Users would *most likely* prefer it's actual purpose (proper Images,
including optimization) instead of reproducibility.

I see. Like Ludo and Mark, I think we should avoid doing tricky things
Could /dev/zero work here? Does it use urandom once, to get a seed, or
does it read urandom repeatedly, expecting different values each time?
Also, I wonder if Guix users would want reproducibility here instead of
longer-lived NAND storage.
