Andi, can you please clarify what you mean by "auto-feeding
/dev/urandom only" and "only get blocking /dev/random with the user
daemon"? Are you suggesting that the kernel provides /dev/urandom and
a userspace daemon (e.g. EGD) provides /dev/random?
Also, if crypto apps like ssh and openssl use on "insecure"
/dev/urandom, then who actually relies on /dev/random? For comparison,
FreeBSD does not even (AFAIK) have /dev/urandom. FreeBSD's /dev/random
is nonblocking (like Linux's /dev/urandom) and includes network
