# Installer WG #7, 2022-12-07


* live demo of Harmonic
    * work to be done...
    * around output / progress
    * uninstalling...
    * aarch64 support in general
* will auto-uid allocation let us drop adding users?
    * let's try enabling it as-is and see how it goes
        * have a new planner or planner option which turns on this option and skips creating users
* how much support should we maintain for old versions of Nix?
    * Probably would publish a build of harmonic for a specific version of Nix?
    * Harmonic already compares the version that was used for installed and makes sure it is compatible with it.
    * Each harmonic release can be aware of minimum Nix versions supported.
* can harmonic be used to update an existing Nix install?
    * right now Nix can already upgrade itself, we should allow Nix to do it.
* should Harmonic support Fedora SilverBlue?
* CI integration in progress
* people who are new to Nix shouldn't use Harmonic, but interested people "in the know" totally could and report problems.
* we'll be publishing tags for consumption when its closer to ready
* `sh`  with `-s`? Rustup uses `-s` and `--`:
