The simplicity of OpenBSD makes it much easier to learn deeply than Linux. Where Linux has tended to create magical veneers over complexity, OpenBSD has tended to simplify the underlying systems.
Also, the OpenBSD project is shouldering the weight of the world and deserves more credit for this. So much of OpenBSD has made it into other parts of the Internet ecosystem.
Like being quite bad for graphics programming and game development.
I think some of us feel that portions of the Linux world have made some wrong or at least undesirable turns for some things. It seems the choice is to either go along with those choices or improve other paths.
Also, not sure what issues you see, but there appear to be a bunch of the standard open source games in OpenBSD as you’d see in Linux. Obviously not the commercial games that have Linux ports, but that strikes me more as an issue of popularity than technical limitations.
Design and implementation are two different things. I can imagine an OS perfect for game programming, but I can't use it, because it's not implemented.
I tried OpenBSD for 2 months, and went back to MacOSX. First, package repositories were meh (either pay, or recompile from source, or never update).
Second, OpenBSD graphic driver support was just very bad - no drivers for GPGPUs.
Third, lack of drivers, applications / services for interfacing with the real world and external devices.
I come home, open my laptop, click on select monitor, and I see 3 monitors available in the WiFi network (two TVs, and a desktop monitor). I can just click one, and my display is mirrored in real time to them - I can play a video, and it is mirrored perfectly, and with audio. Same at work, want to show a video in the presentation room? Connect to the beamer per wifi with a single click, display mirrored, great. Phone detects wifi, laptop backs it up to network storage, synchronizes media, updates software, Smart watch synchronized, etc.
None of that worked with OpenBSD. I had to find a HDMI cable in the basement to connect the laptop to the TV, monitor, beamer,... I had to use a USB cable to connect the phone to the laptop, which I then couldn't back up or synchronize without a gazillion brittle workarounds, etc.
Losing support for all modern devices felt like going back to the stone age. Linux isn't really much better, but while I like OpenBSD design, philosophy, and parts of the implementation. The current implementation doesn't work for me.
Why would OpenBSD be worthy of that expenditure of effort? Because it does some other things very well—perhaps better than Linux (Unix simplicity) and macOS (fully open). Not to mention security.
It sounds like you want a feature set that isn’t in OpenBSD. Fine, use macOS if those features are must-haves for you. Or, if OpenBSD’s feature set is compelling to you, start hacking! As I said elsewhere, I think it’s an easier path to make OpenBSD into what I want than it is to make macOS / Windows into what I want.
As for hardware support, I selected hardware that is well supported by OpenBSD, and it works great. Is there hardware I wish was better supported? You bet. But I’ve felt that way since I started using Linux and BSDs (and OS/2 and BeOS) in the 90s.
In todays world of "throw-away" electronics, there are a lot of devices that I just want to "just work". By the time these are supported on OpenBSD (if I were to implement it), I'll probably be owning a different device.
This is sad, because while I can select the hardware for my laptop, I can't really select the hardware and devices I need to interface with.
Anyone that actually cares about top graphics or game development tooling is either on Apple or Microsoft platforms.
Mac, on the other hand... oh boy. It's pretty much a disaster. There is no end of bugs in Apple's graphics stack, and no, Metal doesn't solve them all. The first time I ran the Metal port of my library, my MacBook Pro instantly kernel panicked. I have never had that happen on Linux.
Besides, the driver is only a tiny portion of the whole tooling for any graphics, professional game engine minded developer.
I'm a professional graphics developer and I prefer the tooling on Linux to that of macOS.
Most professional graphics developer I know rather user better tooling than only bare bones graphics drivers and RenderDoc.
I guess that is the same point of view that gave us OpenGL and Vulkan without any kind of tooling beyond drawing framebuffers with hardware support.
I does appeal to some, but not the majority, otherwise Linux adoption would have moved beyond 1% by now.
Linux desktop market share, or lack thereof, has nothing to do with graphics tooling.
While anyone on Apple and Windows platforms can enjoy Metal Frameworks, DirectTK, Unreal, Unity, CryEngine, PIX, Poser3D, Photoshop, Houdini, Cinema 4D, AfterEffects,...
On Linux, I guess having the freedom to use half baked copies of them, or hunting for libraries that should come out of the box with any graphics stack like 3D math, mesh handling and loading materials, is more important.
I don't know them all, but FYI Unreal, Unity, CryEngine, PIX,Houdini, and Cinema 4D have native Linux versions.
I don't know about Metal Frameworks, DirectTK, Photoshop, and AfterEffects though, you might want to look into that.
In your first comment, when you said "Like being quite bad for graphics programming and game development", you were implicitly forming the larger sentence: "[Retaining] classic Unix sensibilities ... like being quite bad for graphics programming and game development."
And—since the topic of the thread was "OSes that are better because they avoid going down the road of RedHat-like 'modern' Unix sensibilities"—you were implicitly forming a larger assertion: "[OpenBSD, because it retains] classic Unix sensibilities [unlike RedHat] ... [is] quite bad for graphics programming and game development[, unlike RedHat, which is okay at those.]"
And so that's what people tried to argue with you about, which I hope makes people's rebuttals to your first comment make more sense to you.
But then, in your second comment, you went ahead and said that modern Linux is equally bad at doing these things. So clearly the expanded form of your assertion isn't what you meant.
So... what were you actually trying to argue?
I was arguing that only NeXT and SGI had a graphics workstation culture, where having UNIX underneath was more of a detail than anything else.
No one cared that much of writing POSIX daemon and CLI tooling, the whole point was making the best use of the GUI frameworks, IDEs and their GPUs.
Even when SGI offered IrisGL as the basis for OpenGL, they kept the best parts for them.
Either you're talking about high-end gaming, in which case Apple isn't in the game at all - the only players are Microsoft and Sony, though Google is making a bid now as well with Stadia.
Or you're talking about low-end gaming, in which case Google probably matters most because of Android.
The battery life on my X220 was a solid hour less under OpenBSD than under Debian, and it ran some 10 degrees hotter. Yes, this is post-apmd improvements.
I want to like OpenBSD but code correctness just isn't enough for me.
If there was a current port of Docker for FreeBSD and Wi-Fi ac support, it would totally be my daily driver right now. Currently I still use Gentoo on my laptops.
Not saying you'd want to do that, but my understanding is that this is part of a lot of the clever networking you see in orchestration systems.
I haven't had a need to have a jail inspect traffic of another, I suspect that might be tricky. However I've used them successfully as a lightweight alternative to a vm for QA/dev environments -- use hard links for the base OS to save space, and give each jail its own ip and you get fairly cheap multiple boxes. I've also used it them to contain statically compiled binaries -- TLS terminator runs without access to much of anything, if the next vulnerability after Heartbleed was worse, it would be a lot harder to escalate vs common deployment with OpenSSL linked into a webserver; similar with an environment running ffmpeg.
Gentoo maintains forks of udev and logind, imaginatively named eudev and elogind. I use eudev, but elogind is unnecessary for me because I don't use Gnome3. But if that's your thing I'm not stopping you.
Pulseaudio is easy to remove by virtue of Gentoo's source based package model. Dbus less so; many applications have a hard dependency on it.
I think it's possible to use a BSD kernel, but you will very likely deal with a lot of breakage.
Gentoo is just so much easier to administrate that other distros it's unreal.
Alpine Linux
Void Linux (+ Nix package manager)
9front (militant esoterica)
I use OpenBSD on my Thinkpad T410i and Void on an older AMD box. You can use vmm to run alpine images to run docker apps or Linux stuff. My only gripe is firefox runs slowish on OpenBSD though chrome doesn't suffer as such. I use both and only chrome if FF cant handle the site im on.
9front's vmx is mature enough to run an alpine VM and then native x client so the vm runs without an x server and the linux applications run in individual windows giving you a seamless 9front/linux desktop that can run a full browser. This route is only for the truly enlightened ones.
Unix philosophy isn't about keeping the cruft around but building useful systems using simple tools. The idea is do not duplicate functionality if it already exists. I see so many programs attempt to sidestep dependency hell by baking in functionality. This is the overall communities fault and the fault of modern software development which somehow lost the art of pragmatism. The simple part has been long lost in a sea of complexity driven by ignorance and fueled by greed.
