I have used OpenBSD on first a Raspberry Pi 3 and then 4. I liked it, until one day the system stopped responding on either SSH and the serial port, so I had to cut the power to reboot. That's fine, these things happen, but I lost several system files in the process and I couldn't figure out which ones. I only noticed because some things no longer worked and there were some files in /usr's lost+found.
OpenBSD's file system does not have journalling. Their closest equivalent, soft updates, was removed some versions ago, so that they can add journalling later. Until that happens, I will install OpenBSD anywhere again.
That's a shame because apart from that, it really is a good operating system. The documentation is excellent and there are some great services in base. I much prefer OpenSMTPD over Postfix, for example, because it's just a lot simpler and I don't feel unsure if I've missed some option that I really needed to change for the system to be secure.
