Aha!  Thank you.

Inspired by that, I also found 
<https://developer.apple.com/library/archive/documentation/Darwin/Conceptual/KernelProgramming/BSD/BSD.html> 
(from 2013).  Much to read there.

I do remember, though, reading somewhere that there was a continuing 
relationship between Apple/Darwin and FreeBSD, extending even to Apple 
sponsoring FreeBSD development shared with Darwin, with code flowing in 
one direction or the other.  Did I imagine that, or misremember it?

My difficulty in finding any corroboration of that is possibly due to a 
failure of google-fu on my part, and possibly a function of Apple's 
famous degree of cheerful chattiness when it comes to engineering 
internals.

Best wishes,

Norman
