Lix GHA Installer Action

Simple and opinionated action to install Lix. Strictly follows the default semantics of a Lix install.

---

TLDR

It mostly just runs the Lix Installer¹.

Some differences:

• We use the channel: ref to Nixpkgs instead of the flake: ref, as the flake: ref may have issues within the GHA ecosystem, regarding rate-limiting.
• We configure the current user as a trusted user.

Configuring the action

github_access_token

A github token that is added as an entry on extra-access-tokens in nix.conf.

By default, the github.token is configured. See https://docs.github.com/en/actions/security-for-github-actions/security-guides/automatic-token-authentication#permissions-for-the-github_token for a description of the default token's permissions.

extra_nix_config

Additional configuration text to append to nix.conf. See https://docs.lix.systems/manual/lix/2.90/command-ref/conf-file.html for a description of the config file format.
