Hm. Looks legit, no?

I took a look at the recent commit[0] that added most of these:

  “NIST has a randomness beacon available here:
  https://www.nist.gov/programs-projects/nist-randomness-beacon

  It generates entropy at a rate of 512 bits per minute.  Its sent in
  cleartext over the internet, making it unsuitable for cryptographic
  function, it is useful in the generation of entropy for things like
  monte carlo tests or other uses where shared pools of entropy might be
  useful.  As such, lets add the NIST beacon as an entropy source, but
  disable it by default so users have to know to keep it enabled.”

Neat! :-)

I'd be remiss if I didn't point out that it adds 166.3 MiB to the
closure, though. On the one hand, that 's a 240% increase in closure
size for a feature that's ‘disabled by default’ (but read on).

On the other hand, this is a leaf package only installed by users who
want it, and I don't like removing features without better reason. I
also had to add ‘--without-nistbeacon’ to #:configure-flags so it's not
*that* disabled by default...

I'm in mild favour of keeping it, but suggest we add a comment above
those three inputs to point those hacking the recipe in the right direction.

This is still missing a ‘file-name’.

The rest looks & builds nicely.

Thanks!
