I nerd sniped myself and wrote a monster article doing a code commentary of /etc/rc from #OpenBSD 7.8: https://overeducated-redneck.net/blurgh/openbsd-init-system.html
I learned a ton of my base sysadmin skills from studying init(8), and decided to produce a modern version of that (I learned in the 90s).
Also, I have armored my webserver against all bots, and fedi is the only place I syndicate. Boosts are appreciated.
