Nix 2.19.2

• Nix 2.19.1
• enables KVM on linux
• set TMPDIR to avoid potential disk space issues
• don't use the default GitHub token for Enterprise

• always show Nix trace
• Nix 2.17

• Nix 2.16.1
• Fix issues with System Integrity Protection when using macos-12

• pin Nix to 2.15.1 (recent releases broke too many things)
• fix the action to work on custom containers

https://discourse.nixos.org/t/nix-2-14-0-released/25900/4Fix support for Nix 2.14 new profile location: https://github.com/NixOS/nix/pull/5226

• expose github_access_token option and use the default github token by default to prevent rate limiting
• support --no-daemon installation

• Fix nodejs warnings & simplify maintenance
• Use python3 when determining number of cores
• Collapse installer log messages

• curl for downloading the installer is now in quiet mode (since all the bugs have been addressed)
• ensure user profile comes before default profile in PATH
• support https://github.com/actions-runner-controller/actions-runner-controller by using sudo in more places

The last release didn't fix https://github.com/nektos/act correctly.

This release corrects that and adds a test (you need act from master branch).

• Enable flakes and the new CLI by default
• Fix #97: single installation for Act and Docker should be fixed
• Fix #91: retry official installation as it can sometimes return 400

github actions disable Spotlight by default now, so we don't have to do it in this action anymore

• Create X number of users where X = 2 * cpu cores
• Linux: fallback to single-user installation if there's no systemd (support for https://github.com/nektos/act)
• Fixes a subtle bug on self-hosted runners when installation fails

Adds support for install_options that allows passing custom installer options. Run sh <(curl -L https://nixos.org/nix/install) --help to see what's supported.

This feature is useful for installing/testing development versions of Nix.

• Idempotent installation

  Don't run the installer if Nix has already been installed on the host.
  We assume that the installed Nix is already in the desired state.

  This allows to share a given pipeline between hosted and self-hosted
  runners. Usually the self-hosted runners are long-lived and already have
  Nix installed.

  Note that this breaks backwards compatibility if you relied on installing Nix twice with different inputs

• Replaced deprecated GitHub functions
