I used to use OpenBSD, but license wise I'm more pro-GNU. Hyperbola will rebase their OS from GNU/Linux to Hyperbola BSD. The thing is:
- wifi blobs under OpenBSD = easy kernel panics. Atheros ath9k drivers were many times easier to debug
- Ditto with nasty Radeon blobs. The more blobs you have, the less stuff you can understand. Again, these are a good source of kernel panics.
- Blobs from sound SOCs are no better and they look sketchy as hell.
Thus, my daily OS it's a netbook with 9front and I regret nothing.
From GNU, these would be more interesting if they turn into Scheme at full drive, using Coreutils/Findutils and the like just as legacy interop with Unix and they used for instance some weird Lisp based shell as Emacs does with eshell with can do crazy stuff much easier than with SH, which can be crazy difficult to achieve some tasks.
No wonder the Unix folks ran way from it (and from X11) and embraced rc from some Unix v8 at day 1, among rio instead of the X11 disaster. A much easier syntax, no sockets, no bullshit. You know Go's simplicity with dial()? Literal the same there, forget getting crazy with POSIX.
I would love the same from GNU. No Gnome, no Systemd, a Guile based desktop environment, fully integrated with Shepherd, config.scm and the rest of Scheme written tools.
A second Lisp Machine? Maybe, but faster and without 40 minutes long reboots.
