Conditions are something that are on-time evaluated right before we
would start a unit, and cause this starting to be shortcut. That's all
really. Restarts are only triggered when a running service dies, and
the start job queued by that will then check the conditions again. If
the condition doesn't hold then this start will not be executed, and
hence no restart ever again either...

Nope, conditions are not for that. For the specific check of
file-not-empty there's no nice way to handle this, however for
directory-not-empty you could set up DirectoryNotEmpty=...

What precisely are you trying to do?
