I agree with the +/-/= syntax, it's quite intuitive and already seen (chattr). I'd drop the 'set' command here, with some options specified it's implied. Without any it's 'get' btrfs mount-option /dev/... And the 'clear' subcommand could be also dropped with this syntax btrfs mount-option = /dev/... :) BTW, this modifies the defaults only for the unmounted filesystem, but the same should be possible for a mounted one in the future. david -- 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
