 There is no way to test this without binding to the host port, sadly.
 
 ## Deploying

-Nix makes this fairly painless, though, it's simply:
-
-```bash
-nixos-rebuild switch --use-remote-sudo --target-host tlater.net --build-host localhost --flake .#tlaternet
 ```

-This has the added benefit of running the build on the dev machine,
-which is 99% of the time much faster at building than the target
-(though artifact upload may take some time on slow connections).
-
-Note that this also requires the current local user to also be present
-on the target host, as well as for this user to be in the target
-host's wheel group. See `nix.trustedUsers`.
