nix run .#\"<domain>\" will now actually listen for changes in the source repository, and not first copy the entire thing into the nix store.
(since every time we have to change anything on these I get annoyed at having to remember how to build these. Now you can just use `nix run`!)
however, for some reason, ACME still fails. Hopefully it's just the rate limit, but it does look suspicious; there' still a "www.muc.hacc.space" in the log that oughtn't be there …
