<h2 id="what-is-home-manager">What is home-manager?</h2>
|

<p>Before understanding home-manager, it is worth briefly discussing what nix is. <a href="https://nixos.org/">nix</a> is a package manager that originally spawned from a <a href="https://edolstra.github.io/pubs/phd-thesis.pdf">PhD thesis</a>. Unlike other package managers, it uses symbolic links to keep track of the currently installed packages, keeping around the old ones in case you may want to rollback.</p>
|
||||
<p>For example, I have used nix to install the package <a href="https://search.nixos.org/packages?channel=unstable&show=bind&from=0&size=50&sort=relevance&type=packages&query=bind">bind</a> which includes <code>dig</code>. You can see that it is available on multiple platforms. The absolute path of <code>dig</code> can be found by running:</p>

<p>Part of the nix ecosystem includes <a href="https://github.com/NixOS/nixpkgs">nixpkgs</a>. Many popular tools can be found already packaged in this repository. As you can see with these <a href="https://repology.org/repositories/statistics/total">stats</a>, there is a large number of existing packages that are being maintained by the community. Contributing a new package is easy, and anyone can do it!</p>
|
||||
<p>home-manager leverages the nix package manager (and nixpkgs), as well the nix language so that you can declaratively define your system configuration. I store my <a href="https://github.com/davegallant/nix-config">nix-config</a> in git so that I can keep track of my packages and configurations, and retain a clean and informative git commit history so that I can understand what changed and why.</p>

<h3 id="summary">Summary</h3>
|

<p>Installing Podman on macOS was not seamless, but it was manageable well within 30 minutes. I would recommend giving Podman a try to anyone who is unhappy with experiencing forced docker updates, or who is interested in using a more modern technology for running containers.</p>
|
||||
<p>One caveat to mention is that there isn’t an official graphical user interface for Podman, but there is an <a href="https://github.com/containers/podman/issues/11494">open issue</a> considering one. If you rely heavily on Docker Desktop’s UI, you may not be as interested in using podman yet.</p>

As of 2021/11, it is still defaulting to the 1.19 channel, so I overrode it to 1.22 for cgroup v2 support. See the published releases <a href="https://github.com/k3s-io/k3s/releases">here</a>.</p>
