Impure runtime dependencies

[infinisil]

Derivations occasionally need dependencies that are impractical to provide purely in the build, which leads to problems and workarounds. For example:

• Graphics drivers depend on your graphics card, it's impractical to hard-code the driver into all package builds, so NixOS uses /run/opengl-driver/lib. Related: addDriverRunpath: init NixOS/nixpkgs#269475
  • See also topic: what is the issue with libGL on non-NixOS? #55
• Locales
• Glibc nss modules
• Custom CA certificates
• Timezones
• ...

I previously sketched a potential solution here: https://gist.github.com/infinisil/3366e7dfc9a01f6eeb25b5cb475cc585

We decided to focus on this topic for this weeks Nix Hour, this Friday at 15:00 CET! If you have any questions about this topic, either:

• Ask them in this issue in advance with a comment
• Join the meeting and ask using voice or chat

And if you just want to listen in, it's going to be streamed to YouTube here 🙂

Today I had issue with glibc nss on rhel linux. Solved by:

ln -s /lib64/libnss_sss.so.2 /nix/store/qn3ggz5sf3hkjs2c797xf7nan3amdxmp-glibc-2.38-27/lib/libnss_sss.so.2

I don't like non-Nixos problems 😞

Yeah it's not great, lot of improvement potential!

For now I'll close this issue since we talked about this last time :)
