BTW, any good idea for btrfs to do such operation like enabling/disabling some minor features? Especially when it can be set on individual file/dirs. Features like incoming write time deduplication, is designed to be enabled/disabled for individual file/dirs, so it's not a quite good idea to use mount option to do it. Although some feature, like btrfs quota(qgroup), should be implemented by mount option though. I don't understand why qgroup is enabled/disabled by ioctl. :(
mount option won't persist across systems/computers unless remembered by human.
