When you upgrade NixOS there are always warnings on anything deprecated telling you what to do.

I guessed so. So it’s not at all done once, never done again as the OP suggested but rather done once, now keep redoing something slightly different every fortnight and enjoy your constantly half-broken system. In a way, it’s reassuring to see that niche Linux distributions have changed so little in the decade since I last used one.

this is presumably why guix calls itself "an advanced packaging management system". if you don't want to futz around with that kind of thing theres always ubuntu which mostly just works and even comes prebaked with activedirectory support so you can argue with your IT department about it :)

Yeah, if any of that is even remotely true then something is horribly wrong with your system.

I only yet this once every 6 months. And the issues are resolved in minutes following the printed instructions (as opposed to crawling through arch wiki or whatever).

Most of the time the deprecations require no action on my part, I simply rather keep things tidy and make the warnings go away.

You are misunderstanding what I am saying. The situation is very different. There are still Linux/Wayland/NVidia/Whatever issues, but configuring NixOS is not among them.

Here to confirm that you can usually ignore those warnings for a year or more, hahaha.

What exactly is the point of this comment? You haven’t even tried the distro, was assumed something wrongly, and then double down on it?

In that case NixOS rebuild will fail telling you exactly what to do. This is better than upgrading MacOS, where a system upgrade may break tools installed with homebrew and there is no way of knowing until _after_ the upgrade.

For those not familiar:

Nix tooling introduced flakes. The community generally likes this feature since it provides a couple of significant improvements on how nix gets used.

There was a breaking change between 2.3 and 2.4 for even the non-flake code; but, that was partly because 2.4 was a huge release. (2.3 released in 2019/09; 2.4 in 2021/11). Releases since then have been smaller and more frequent.
