Thanks, > > Josef Hi Josef, (Said in another thread) I'm ok with either one, but... from some reports on the list, end users are more likely to control, use chattr files by themselves, inheriting flags via moving a file to a new directory is indeed not very welcomed. So for practical use, I assume that it's fairly enough to inherit flags only on creation? thanks, liubo -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
