Config
Flakes:
$ deploy --interactive '#fwminex'
$ nix build .#deploy.nodes.fra1-c.profiles.system.path
Other:
$ nix build .#nixosConfigurations.vno3-rp3b.config.system.build.toplevel
$ nix eval .#nixosConfigurations.fwminex.config.services.nsd

Encoding host-only secrets
Encode a secret on host:
rage -e -r "$(cat /etc/ssh/ssh_host_ed25519_key.pub)" -o secret.age /path/to/plaintext
Decode a secret on host (to test things out):
rage -d -i /etc/ssh/ssh_host_ed25519_key secret.age
