Hi,

the main reason for urngd was size, because I plan to have it included in all
default firmware images, even for tiny devices with 4MiB of flash space. The
kernel machinery is more heavy as it have more features.

could you please point me to that email thread? What's your plan now? Do you
simply plan to maintain it as out of tree kernel module forever or do you plan
to eventually address the comments leading to the reject and try it again
later?

Thanks a lot for your great work!
