Somethings I have routinely encountered in recent years, reviewing this stuff, are:
[1] When I report something that went wrong, xBSD users are very quick to castigate me, call me a liar, tell me I am incompetent, that things are fake news, etc.
[2] When I bother to chase things down, talk to the developers, etc. then they confirm that what I found was real, correct, and true -- but they never thought anybody would do that stuff.
It shocked the FreeBSD folks that VirtualBox defaults to BIOS firmware in 2025... and it labels UEFI as "experimental". What I said was correct: FreeBSD cannot readily boot from ZFS on MBR on a BIOS system. And no, it is not documented. They didn't think anyone would try, and they didn't know the defaults of the single most common cross-platform FOSS hypervisor.
Similarly, default CUA key bindings like Ctrl+left and Ctrl+right don't work and tend to emit garbage when used on the console. These are absolutely standard CUA defaults for the PC platform, but not in BSD. I don't know what it uses, maybe Vi keystrokes -- I learned that in 1988, hated it then, and never use it if I have a choice -- or Emacs. I refuse to use Emacs. I don't have a Meta key and neither does anyone on the Emacs dev team. Ain't got time for that 1970s nonsense.
My attitude is: run on the PC? Adopt PC standards or GTFO. This upsets BSD folks who think their '70s VAX standards or whatever are perfectly fine.
That's fine. I will continue pointing out the stuff that doesn't work until someone fixes it. I am sure there will be plenty of other stuff that doesn't work. It's not like there's a shortage.
