What would be performance with proposed changes when running command below ?

dd if=/dev/random iflag=fullblock of=file.bin bs=1024 count=1024 status=progress

[zx2c4]

No changes. Totally unrelated.

I meant /dev/urandom, sorry.

Do you mean it is in reverse, in sense what getrandom() would be using ?

Still no changes. /dev/urandom will block until first seeded at boot. By the time you can run `dd`, it's seeded, because the system needs to have booted for that.
