@Funkpirata I'm running #NetBSD (I know that's not OpenBSD, but not sure how much a requirement that is) on a 5 or 7 year old Raspberry Pi. No complaints. Super easy install, running like a champ. Total cost: $15 NZ, used.
@Funkpirata If this helps at all, here's me talking about my NetBSD-on-Pi experience, plus some potentially useful links:
Wow you do many of the things. I'll give some of your podcasts a listen ;-)
@klaatu
Oh cool is it a pi2? I have one I use for kodi. The only Unix like system I have played with is gnu/Linux. I just have an interest in learning and network/information security so openbsd seems like a good os to play with. I'll try putting netbsd on it and have a play around. I just then purchased a Lenovo T500 that I plan to flash with libreboot using my RPI, and I'll use that to play around with openbsd. Also pretty keen on picking up a firefly-RK3399 cause it's awesome!
