Config

Flakes:

$ deploy --interactive '#vno1-oh2'

$ nix build .#deploy.nodes.hel1-a.profiles.system.path

Other:

$ nix build .#nixosConfigurations.vno1-rp3b.config.system.build.toplevel

Debug

$ nix eval .#nixosConfigurations.vno1-oh2.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
