Since you've been on the ride since '04, I'm curious to hear your thoughts. How do you feel the maintenance burden compares today versus the GCC 3.x era? With the modern binhost fallback and the improvements in portage, I feel like we now spend less time fighting rebuild loops than back then? But I wonder if long time users feel the same.
I'm another one on it since the same era :)
In general stable has become _really_ stable, and unstable is still mostly usable without major hiccups. My maintenance burden is limited nowadays compared to 10y ago - pretty much running `emerge -uDN @world --quiet --keep-going` and fixing issues if any, maybe once a month I get package failures but I run a llvm+libcxx system and also package tests, so likely I get more issues than the average user on GCC.
For me these days it's not about the speed anymore of course, but really the customization options and the ability to build pretty much anything I need locally. I also really like the fact that ebuilds are basically bash scripts, and if I need to further customize or reproduce something I can literally copy-paste commands from the package manager in my local folder.
The project has successfully implemented a lot of by-default optimizations and best practices, and in general I feel the codebases for system packages have matured to the point where it's odd to run in internal compiler errors, weird dependency issues, whole-world rebuilds etc. From my point of view it also helped a lot that many compilers begun enforcing more modern and stricter C/C++ standards over time, and at the same time we got Github, CI workflows, better testing tools etc.
I run `emerge -e1 @world` maybe once a year just to shake out stuff lurking in the shadows (like stuff compiled with clang 19 vs clang 21), but it's really normally not needed anymore. The configuration stays pretty much untouched unless I want to enable a new USE for a new package I'm installing.
its been years since I had a build failure, and I even accept several on ~amd64. (with gcc)
Anyway, to answer grandparent, I basically never had rebuild loops in 19 years.. just emerge -uU world every day or sometimes every week. I have been running the same base system since..let's see:
qlop -tvm|h1

I do engage in all sorts of package.mask/per-package use/many global use. I have my own portage/local overlay for things where I disagree with upstream. I even have an automated system to "patch" my disagreements in. E.g, I control how fast I upgrade my LLVM junk so I do it on my own timeline. Mostly I use gcc. I control that, too. Any really slow individual build, basically.
If over the decades, they ever did anything that made it look like crazy amounts of rebuilds would happen, I'd tend to wait a few days/week or so and then figure something out. If some new dependency brings in a mountain of crap, I usually figure out how to block that.
I tried Gentoo around the time that OP started using it, and I also really liked that aspect of it. Most package managers really struggle with this, and when there is configuration, the default is usually "all features enabled". So, when you want to install, say, ffmpeg on Debian, it pulls in a tree of over 250 (!!) dependency packages. Even if you just wanted to use it once to convert a .mp4 container into .mkv.
You are trading off having a system able to handle everything you will throw at it, and having the same binaries as everyone else for, well, basically nothing. You have a supposedly smaller exploitable surface but you have to trust that the Gentoo patches cutting these things out don't introduce new vulnerabilities and don't inadvertently shut off hardening features. You have slightly smaller packages but I'm hard pressed to think of a scenario where it would matter in 2026.
To me, the worst debuggability and the inability to properly communicate with the source project make it a bad idea. I find Arch's pledge to only ship strictly vanilla software much more sensible.
Additionally gentoo has become way more strict with use flag dependencies, and it also checks if binaries are depending on old libs, and doesnt remove them when updating a package, such that the "app depends on old libstdc++" doesnt happen anymore. It then automatically removes the old when nothing needs it anymore
I have been running gentoo since before 04, continously, and things pretty much just work. I would be willing to put money that I spend less time "managing my OS" than most who run other systems such as osx, windows, debian etc. Sure, my cpu gets to compile a lot, but thats about it.
And yes, the "--omg-optimize" was never really the selling point, but rather the useflags, where theres complete control. Pretty much nothing else comes close, and it is why gentoo is awesome
I'd say "the fastest" is a side effect of "allowing one to tune their systems to their utmost liking." -march=native, throw away unused bits and pieces, integrate modules into the kernel, replace bits and pieces with faster -- if more limited -- bits and pieces. And so on.
