I like nix and its approach but if I'm being honest I think its also getting easier to be sloppy about dependencies and ask AI to find any dependencies that might be missing from the cleanly installed packaging metadata. There's maybe a paradox for developers in that we can try to drop structure and brute force scan first intensively enough to catch anything likely to get caught or we can ask AI to finally apply all the rigorous methods we decided were too expensive for routine software and probably have minimally more things to run with each release.
I found that reducing my "Linux" lines from ~21000 (including net-pf-16-proto-21) down to those ~3000 I might actually use (e.g. udp_tunnel) to be a fairly effective method of not having to care about each and every newly discovered memory safety hazard.
I remember my earlier days of Linux of having to compile a kernel module to read from cdrom. Seems like Linux has gone too far in the other direction of having modules that you will probably never need.
That's the same thing that people say about MS Office: nobody uses more than 15% of its feature set, but everyone uses a different 15%. "Linux" having these modules is what keeps it relevant and prevalent in different fields and niches. Whether distro's should ship this many modules by default is a different question, but then we're no longer talking about Linux the kernel.
There has been so much discussion about the increase of volume in CVEs. I love that it's super apparent from looking at that graph of CVEs by year, there is a noticeable bend in the slope upward in the 2026 plot. It's not just hype, the rate of CVEs is changing faster than prior years.
