DeterminateSystems/nix-installer v0.5.0

on GitHub

This release includes some more work towards supporting installing over existing installations (see #126 for more information on our curing effort). Specifically, an existing /etc/nix/nix.conf file will no longer be a hard error¹ and will instead be merged with the settings that we desire.

It also fixes a few bugs, like a typo in a permissions check (checking a file had a mode of 664 instead of 644), a macOS installation bug that affected some setups (see #295 and #298 for more information), and explicitly erroring on WSL1 as unsupported.

If you rely on us as a library, the change that will impact you the most is that we made all of our error enums #[non_exhaustive], so that adding new variants in the future won't require a new major version.

The diagnostics report also saw a slight rework to be somewhat more useful in actually diagnosing issues. A diagnostic report now looks like this:

{
  "version": "0.5.0",
  "planner": "linux",
  "configured_settings": [
    "modify_profile"
  ],
  "os_name": "Ubuntu",
  "os_version": "22.04.1 LTS (Jammy Jellyfish)",
  "triple": "x86_64-unknown-linux-musl",
  "is_ci": false,
  "action": "Install",
  "status": "Failure",
  "failure_chain": [
    "Action(\"configure_nix\")",
    "Child(\"place_nix_configuration\")",
    "Child(\"create_directory\")",
    "CreateDirectory(\"/etc/nix\")"
  ]
}
