Can you just use it without changing the code of the reset handler?

I didn't know that, thanks for pointing it out. I'll take a closer look
at it before reposting.

Seems a bit tricky because the device tree has to be rebuilt at reset
time (including snapshot load), but it uses the random number. So

It seems strange to me, that loading the existing configuration has to randomize the device tree.

having a second nosnapshotload reset function might not be called in
the correct order, I think?  For now I will keep it as is.

Ok, let's wait for other reviewers.
