A few small things I spot, but overall it's looking really good, definitely way better than inxi 3.3.01 if you want compare, that's the same install: wget
https://smxi.org/inxi and so on.
I was slightly shocked when I tested the BSDs, now and then, like now, I dive into getting BSD stuff working, and it's always quite dismaying to see just how much has broken over the space of a year or two or three. On the bright side, I never really had NetBSD support at all, and now I do.
Good to see the removable type working for drives, it's all delicate pattern matching. I've removed some openbsd specific tests internally, and made all the detections more generic, that helped get netbsd working a lot better since many of the openbsd detections work fine for netbsd stuff, I just was never able to get netbsd running before.
I'm still puzzled by why openbsd is failing to get the virtual terminal for running in, but this stuff gets pretty arcane pretty quickly, so I will just make a note of it being a thing, and maybe one day in the future Ill learn a key bit of missing info. I'm suspecting that because it's pinxi running, not you directly in terminal, openbsd doesn't have the terminal data available, but I don't know, it's hard to diagnose that one, and it's a small point.
As you can see, pinxi is turning into a real memory hog, basically to speed up its operations, it dumps as much stuff into ram as quickly as it can so it can then proceed to work with the data in ram, not off disks or subshells, but that has a cost, of course, but only for a second or so.
Thanks a lot for testing and showing some data, this openbsd looks pretty good I have to say, best it's ever been, by quite a margin.
The /dev/sd size is failing, if you can run: dmesg | grep ^sd
and show the output, that will show if the pattern is just failing, or if the data just is not there. That's the only real error I see, plus the duplicated drivers in one place, that should have been filtered out but i didn't realize there were situations with two drivers listed in the first place there.
