OpenBSD's Security Model Challenges Modern Linux Architecture and 32-Bit Support

Open Source & LinuxApr 18, 2026score 1.133 posts · 10 replies across 3 instances
A persistent technical thread centers on the value of highly portable, security-hardened, UNIX-like operating systems, specifically NetBSD, OpenBSD, and Plan 9. Users are actively seeking viability for 32-bit operating systems following major distribution drops. The primary conflict pits the ideological commitment to code correctness (championed by [email protected]) against the practical necessities of modern hardware and software. [email protected] vocally advocates for OpenBSD as a daily driver, specifically targeting the perceived security weaknesses in systemd and the integration of AI/Rust into the Linux kernel. Meanwhile, [email protected] confirms the real-world difficulty of running old architectures, citing Debian's removal of 32-bit support. The consensus favors minimalist, verifiable operating systems. While Plan 9 remains an area for expert-level debugging ([email protected]), the most pronounced technical debate focuses on adopting OpenBSD's 'security by correctness' principles, viewing them as superior to the perceived architectural fragility of complex systems like Qubes OS.

Key points

SUPPORT
OpenBSD is being adopted as a daily driver due to its 'security by correctness' focus.
[email protected] stated the switch to OpenBSD for peace of mind, praising 'pledge/unveil' mechanisms.
OPPOSE
Concerns persist regarding modern Linux development direction.
[email protected] expressed deep skepticism about security risks introduced by AI and Rust in the Linux kernel.
SUPPORT
The difficulty of maintaining 32-bit compatibility is a tangible user problem.
[email protected] noted looking for a viable 32-bit system because Debian dropped support.
SUPPORT
NetBSD is highlighted for its clean code and portability, with calls for funding.
[email protected] specifically called for community donations to support NetBSD's continued development.
OPPOSE
Qubes OS architecture is criticized for introducing systemic fragility.
[email protected] pointed out that Qubes OS relies on Xen, Linux, and Fedora, creating unnecessary fragility.
MIXED
Debugging esoteric Unix systems requires deep technical collaboration.
[email protected] offered specialized help debugging Plan 9 kernel issues, demanding serial console trace data from [email protected].

NetBSD turns 33 this Sunday! 🚩 To celebrate 33 years of clean code, portability, and zero bloat, Challenging the rest of the fediverse to help hit this year's funding goals. Also do drop a screenshot of your uptime, uname -a, or a pic of the weirdest hardware you've got running NetBSD right now. (RockPro64 NPF routers or Pi's hooked up to retro CRTs highly encouraged). Throw some money at the developers keeping the real UNIX alive: https://www.netbsd.org/donations/ #NetBSD #UNIX #RetroComputing #OpenSource #runbsd #FreeBSD #OpenBSD #Linux

No #Netbsd No #plan9 No #Haiku #OpenBSD crashes after awhile #Deuvan and #Windows2000 works But i am looking for a viable #32bit system Since Debian dropped 32bit damn you 🤣 #compac #oldcomputers

Between work, creative work, house work, self-hosting, tinkering and bricking stuff, eating and sleeping... not much time left for participating in the fediverse, not that I have much to say yet... I do have to say now one thing: for my peace of mind, I've decided to get into #OpenBSD and make it my daily driver. I'm also thinking of removing all of the Mint installs I still have and go completely #systemd-free - I'll dual boot #Linux on some of my machines, but that's it. Torvalds once quipped: "I think the OpenBSD crowd is a bunch of masturbating monkeys"... Whereas Theo de Raadt said that Linux may be for people who just hate Windows, but OpenBSD is for people who love UNIX - and when I read that, I realized I was a Windows hater, but now I'm something more than that. It's not systemd I'm most concerned about though, but the direction of the Linux kernel, with AI and Rust possibly creating even more security issues... I just got a bad feeling. If Mythos discovered a single mere DoS bug in the whole OpenBSD code codebase, that probably means its devs were actually right on insisting on security by correctness above all. I still like Qubes OS, but it relies on Xen, Linux and, worst of all, Fedora. It can provide the best security in certain regards and it is easy to use as long as you stick to the defaults... But there's something fragile about it. The trolls who are mocking Qubes and insist on glorifying OpenBSD might have a point after all. While my Qubes PC is still a WIP, I wanted to harden my Alpine and also to resume customizing it - both turned out not how I wanted... So I've decided to install Artix on the side for the tinkering urges, but otherwise spend time on OpenBSD - with its security by default approach that makes worth the efforts of putting up with the rough edges an otherwise smooth installation and post-install still has - and get used to CWM, which looks fine enough with picom. CWM is in the base system, so it's most trustworthy - but I do still feel sometimes the urge to get back to i3/sway... Oh well, we'll see. Did I mention how genius I think pledge/unveil are? Brilliant stuff, I just wish they had more browsers patched with it. If I had all the time in the world, I might've tried doing that myself.
