At the moment in debian & ubuntu, btrfs tools package ships udev rules to call "btrfs scan" whenever device nodes appear. If scan is built into mount, I would be able to drop that udev rule. There are also some reports (not yet re-verified) that such udev rule is not effective, that is btrfs mount fails when attempted before udev has attempted to be run - e.g. from initrdless boot trying to mount btrfs systems before udev-trigger has been run (to process "cold-plug" events). -- Regards, Dimitri. -- 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
