VM:

$ nix build .#nixosConfigurations.vm.config.system.build.vm

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
