    If paths are different than default, they need to be specified in the config and the service
    needs to grant read/write permissions.
    CUSTOM_PATH and WORKDIR are environment variables.
    I'm not sure about `log` tbh. Per the official docs, the default is empty.
    This might cause duplicate entries if the user did not specify in all-lowercase.
    Also, it will not overwrite custom configuration, which might make the installation fail.

    If the secrets were not provided, generate them here. Since grains.get_or_set_hash was
    removed, there is no easy way to cache the random value to avoid changing it over and over.
    It cannot be read from `app.ini` since the configparser serializer throws an exception.

    Generating it here avoids
      a) calling the gitea binary in the app.ini template (`gitea generate secret SECRET_KEY`)
      b) and special-casing to avoid regenerating those secrets every run.

    The INTERNAL_TOKEN has a special format, but it can be configured to be read from a separate file.
