Re: Not the only one...
Yes, I was going to say the same. BSD as an OS dates back to 1977 or so and the likes of FreeBSD, NetBSD and OpenBSD are direct genetic descendants, not re-implementations.
(Currently running FreeBSD 12.3 RELEASE here, on two desktop, this laptop and on my file server - Thinking about upgrading to 13 now that 13.1 is out - I still don't like n.0 of anything :-))
