The error was:
```
internal/certauthority/certauthority.go:68:15: err113: do not define dynamic errors, use wrapped static errors instead: "fmt.Errorf(\"expected CA to be a single certificate, found %d certificates\", certCount)" (goerr113)
return nil, fmt.Errorf("expected CA to be a single certificate, found %d certificates", certCount)
^
exit status 1
```
I'm not sure if I love this err113 linter.
I think we may still split this apart into multiple packages, but for now it works pretty well in both use cases.
