We might want to update our Rust version.
It can be done by changing the commit of Nixpkgs we use.

But we must also update our cache (nix.web.deuxfleurs.fr) with some Rust compilers as we don't want to recompile them when the runner's cache is flushed or cold. This is the complex and slow part of the process.

We should also document the process to make it easier for me, and allow other people to do it easily.

We also might want considering Nix Flakes and/or create profile to have a more clever garbage collection at the runner level (I suspect that the whole cache is flushed each time the GC is run because all the build derivations are dangling ones).

Also consider changing musleabihf to musleabi on ARM to extend our compatibility. The impact of not forcing hard float seems to be limited for ARM CPU that have a FPU.

We should also update the containers that we use. Currently, we are running nixos-21.05 but nixos-21.11 is available and soon nixos-22.05.
