First attempt at NixOS build
These configurations were copied[1] and heavily modified. The general modification strategy was to remove as much as I could without breaking things. Later, I'll add customizations back go the nixos configurations. The VMware build comes from comments[2]. This commit tests if the vmware build works. I am editing from a Mac, so I am relying on Github actions to test the nixos and vmware artifact build. References: 1. https://github.com/mitchellh/nixos-config/tree/01fcaea3bdcd47540da39446d80e85d042a70cc1 2. mitchellh/nixos-config#1
