Sadly, my enthusiasm was premature: the Kaveri doesn't have a hwrng. So
although I've enabled the device under the HW_RANDOM options, nothing
comes out and this "fix" will only work for some machines.

For me, I'll have to go to plan B (revise the bootscript and/or patch unbound).
I see that Nixos seems to bind /dev/urandom to /var/lib/unbound/dev/random
so I guess that ought to work. Sorry for the noise.
