[Nix-dev] Why is rngd running by default?

[Peter Simons]

Hi guys,

it appears that my NixOS host now features an rng daemon that's started
by default. According to the man page, its purpose is to "feed random
data from hardware device to kernel random device". The hardware device
is supposed to be located at "/dev/hwrandom", but my machine doesn't
have any such device. So I wonder why I'm running that daemon? Does it
serve any purpose in the absence of special hardware?

Take care,
Peter
