Good thing I'm still on wheezy I suppose.  For some reason it managed to
seed at start.  I wonder how that got dropped in the transition.

Strangely, though, /dev/urandom by default is not fully reseeded when
the Pi is being used in a server mode and no real mention of that is
made.  The entropy stays very low.  I had to install rng-tools to have
the hardware RNG hooked to /dev/urandom to boost the entropy while running.
