Ideally we would have subclasses of `LocalDerivationGoal` that provide the platform-specific code for building (such as sandboxing). Or create some abstract interface for build execution that `LocalDerivationGoal` can use.

This means that Nix fails in this bit of code: ```c++ /* Drop additional groups here because we can't do it after we've created the new user namespace. */ if...

Team discussion: * This would be a useful feature. It can be implemented in `MixEnvironment`. Probably `nix run` should inherit from `MixEnvironment` as well, that way all environment-related flags would...

@DamienCassou Can you reproduce that with a more recent Nix version? I couldn't reproduce it (either with 2.28.5 or master on macOS). I tried: ``` > cat foo.nix ~/crash/x {...

It means that the registry entry is only used to rewrite the given flakeref if it's exactly equal to the `from` of the entry. This is useful if you have...
