My personal nix configuration leveraging:

• NixOS
• Determinate Nix
• Dendritic Nix

• nix-darwin

Hosts a Dell XPS 9500 laptop, a NixOS PC, a NixOS VPS, and an Apple silicon MacBook.

• laptop: Dell XPS 9500 workstation.
• desktop: NixOS workstation. Vaultwarden at vault.barrettruth.com, delta at delta.barrettruth.com, and finance.barrettruth.com.
• vps: NixOS VPS. Authelia at auth.barrettruth.com, Headscale at headscale.barrettruth.com, and the static sites (barrettruth.com, barrettruth.sh, philipmruth.com, vimdoc-language-server.com, ts.barrettruth.com). forge.barrettruth.com and git.barrettruth.com redirect to GitHub.
• mac: Apple silicon MacBook, built from .#darwinConfigurations.mac with just rebuild-mac.

One thing on the mac is set once per machine and cannot be declared: a still image has to be chosen as the wallpaper in Settings > Wallpaper. macOS ships a dynamic wallpaper, and while one is active WallpaperAgent renders over anything NSWorkspace.setDesktopImageURL sets, so ctl wallpaper gen reports success and changes nothing.

The baremak layout is installed to /Library/Keyboard Layouts and enabled through AppleEnabledInputSources, so it needs no setup, but a newly enabled input source only reaches the menu bar after a logout.
