Current udev ships rule that calls equivalent of "btrfs device ready $dev", where $dev is the canonical kernel device name. btrfs kernel driver will update internal list of device names when it gets this ioctl, which means that unless you explicitly pass full list of /dev/disk/by-*/* during mount you will see those kernel names. And even then as soon as device for some reason dis- and re-appears (as is apparently the case here) it will be renamed back by udev when "add" event is seen. -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
