Yeah, if you allow a separate /usr partition to be mounted later, all stuff executed in udev rules should be put in either /bin or /sbin. The same is true for /var/lib/alsa. And yet the question is whether we should suppress the error in such a case. When suppressed, user might not notice what went wrong. Meanwhile an error message is annoying if you know it.
