I remember sticking something in to improve entropy, and ripping out a patch to hostapd that tried to manufacture it. right now I'm merely trying to stablize the new bits - dnssec for dnsmasq 2.73rc1, babel-1.6 (not in this build) with procd and ipv6_subtrees and atomic updates, get someone F/T on the minstrel stuff, and get heads down on per station queuing by mid april. I was not expecting to make chaos calmer with the last at all and am still not, and next up is getting some profiling infrastructure in place that actually works....

For general purposes, seed a good RNG once before first use, us= ing /dev/urandom, then just keep pulling values from it as needed.
