AFAIK the netflix CDN boxes all run -current (they used to at least), so is the main pfsense release.
-current is definitely ok for production
-current is ok with the caveat that you have to be pretty engaged with the development process, ideally having developers employed (or be one yourself)
I was a committer long ago, these days sticking to latest releases on my boxes
Desktop is a moving target and modern hardware usually requires -current, but I wouldn’t call it “production”
No not all. I’m only on 16 for RDNA4 support, might go back to 15 once it’s back ported, if I can be bothered.
The command I referenced is not, I guess 16 only. Other examples are the service command just appearing, etcupdate being preferred to mergemaster, whatever the current preferred flavour of port upgrade tool is (poudrire, portmaster, portupgrade, something else(?)).
I also have no idea what is a sane way to do things that Linux does as systemd user services like pipewire, xdg-sessions if I want to share my screen.
I think for etcupdate etc, you should be able to get that info from /usr/src/UPDATING
For port upgrades, I dunno if it applies to CURRENT, but pkg seems to work?
I usually read the release notes for each release, which keeps me up to date enough.
I dunno about your session question. In X11, you could drop those in .xsession, but Wayland is a just a protocol, so who knows.
Yeah pkg is fine if you’re using prebuilt packages. I don’t think it builds ports with custom configs for you from /usr/ports. Or maybe it does now and I missed that too.
I much prefer sway as my desktop, but each to their own.
