Hmm, 233dac2 doesn't build for me on x86_64-linux. I wonder how OfBorg managed it…

Works for me on another system with a more recent Nix so probably a Nix bug that got fixed along the way.

Okay, as it turns out this package should have failed to build, and only worked due to a regression in Nix.

From the OfBorg log:

Installing /build/source/build/data/org.freedesktop.ModemManager1.conf to /etc/dbus-1/system.d

This should not have worked.

We can set -Ddbus_policy_dir to fix D-Bus file installation, but the new example files can't be disabled. I've opened an upstream MR to add an option to disable installing those.

Ugh I assumed the option is not necessary anymore due to the path being properly interpolated now but did not notice that it is interpolating sysconfdir. Must have been using Nix 2.12 as well.

But that line does not really make sense – it is getting sysconfdir from the pkg-config file and then replacing it wholesale with sysconfdir of the package. And the /etc path is deprecated for packages anyway.

As for the examples, it might be useful install them, maybe with something like https://github.com/NixOS/nixpkgs/blob/532f202b6490c646817796ba09e88c8b7bea74c1/pkgs/os-specific/linux/firmware/fwupd/add-option-for-installation-sysconfdir.patch

Useful for what? I don't mind installing stuff like that when it doesn't cause problems, but I'm fairly doubtful that people are going to go poking around in their Nix store to find examples.

When I want to edit fwupd settings on my NixOS system, I find running nix build .#fwupd in my config flake and looking at the commented config files in the output more convenient than looking at the fwupd version in the nixpkgs input of my flake, going to the repo and looking up the source file for the config with appropriate tag. But it’s just a nice to have, not something critical.
