Could we also do this in one expression?

    (typeattributeset file_type (or guix_profiles_t
                                    guix_daemon_conf_t
                                    guix_daemon_exec_t
                                    guix_daemon_socket_t
                                    guix_store_content_t))

I also think we need to declare our use of “file_type” first:

    (typeattribute file_type)

What do you think?
