This reverts commit 2edc017a6e0cb92b72b768aaa46c6d336ad84eff. We shouldn't be using a shell script here, but the SeedRNG integration into OpenWRT requires a bit more thought. Etienne raised some important points immediately after this was merged and planned to send some follow up commits, but became busy with other things. The points he raised are important enough that we should actually back this out until it's ready to go, and then merge it as a cohesive unit. So let's revert this for now, and come back to it later on. Cc: Etienne Champetier <champetier.etienne@gmail.com> Cc: Petr Štetiar <ynezz@true.cz> Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
