Happy #FreeBSDDay! After a couple of years of playing with Linux, I grabbed a FreeBSD ISO and played with it on Virtual PC (pre-Microsoft). I think it was 4.7-RELEASE?
I gathered some old machines and ran FreeBSD, NetBSD, and OpenBSD on each. Ran OpenBSD as a router (not having ANY idea what I was doing). Settled on FreeBSD for many years, but have branched back out since. Local DNS is NetBSD on an RPi, VPS web server is OpenBSD.
