# Partitioner with multidevice BTRFS

* Show multidevice BTRFS in the general list of devices.
* Mount point and label is empty for the devices belonging to a multidevice BTRFS.

## New `Type` column

Columns `Type` and `Fs Type` will be merged into a new `Type` column on steroids:

* Blk Device without fs:
	* not used:
		* Disk: vendor
		* Partition: partition id
		* RAID: RAID
		* LV: LV
		* Bcache: Bcache
	* used as PV: PV vg1
	* used by RAID: part of md0
	* used as backing Bcache: part of bcache0
	* used as caching Bcache: Bcache caching

* Blk Device with fs:
	* no multidevice fs:
		* Disk: EXT3 disk
		* Partition: EXT3 partition [1]
		* RAID: EXT3 RAID
		* LV: EXT3 LV
		* Bcache: EXT3 Bcache
	* multidevice fs: part of BTRFS (/)

* LVM VG:
	* always: LVM

* Multidevice BTRFS:
	* always: BTRFS

[1] for some cases, the filesystem type is not enough (e.g., ESP).

## Questions

* Can a device belonging to Btrfs be encrypted?
