I'd guess this is about the distribution of blocks within the image, so

Any pointers about that subject ?
This looks strange as I'd have thought that less writes => less wear.

Hi Mark,
those are all good points.
In this specific case the randomness is necessary for NAND wear levelling,
so getting rid of it isn't good anyhow.
I'll investigate whether there is a way to defer invocation of
the randomizer so that the user can invoke it in the installed package.

I’d be wary of introducing a static /dev/urandom. It could do

I think it would be better to patch software as needed to avoid t

You could use /dev/zero
Hi,
u-boot tools/sunxi-spl-image-builder.c reads from /dev/urandom .
For reproducibility I'd like this to be a static file. Do we already have one
for this purpose?
