How to find the maintainers of a module

I have created a nixpkgs PR for the oci-containers module. I would like to ping the maintainers of the NixOS module, but I do not know, how to find them. While package maintainers are mentioned in the package metadata, I could not find a maintainers field in the module.

How do I find their github handles to ping them?

There usually aren’t maintainers for modules. You can see who last touched the module files and ping them (ignore treewide commits). You can also assume that people who maintain the package may also be interested in the module.

About a third of NixOS modules do have a meta.maintainers field. It’s not the majority but it’s not so rare I’d call it ‘unusual’.

Another place to check is the ci/OWNERS file.

The oci-containers moldule has no maintainers, no corresponding package nor owner. I have pinged some people, who have touched the module multiple times recently.

It’s tightly coupled to the docker and podman modules/packages, and at least the packages of those have maintainers.
