Comment # 36 on bug 994883 from Rich Coe

If this creates the uaccess data, I think this change in systemd-232 might
fix this.

if (streq(subsystem, "drivers")) {
        /* the 'drivers' pseudo-subsystem is special, and needs the real
subsystem
         * encoded as well */
        r = asprintf(&id, "+drivers:%s:%s", device->driver_subsystem, sysname);
        if (r < 0)
                return -ENOMEM;
} else {
        r = asprintf(&id, "+%s:%s", subsystem, sysname);
        if (r < 0)
                return -ENOMEM;
}
