	  Build a btrfs root filesystem. If you enable this option, you
	  probably want to enable the btrfs-progs package too.

	string "filesystem label"

config BR2_TARGET_ROOTFS_BTRFS_SIZE
	string "filesystem size"
	default "100m"
	help
	  The size of the filesystem image in bytes.
	  Suffix with k, m, g or t for power-of-two kilo-, mega-, giga-
	  or terabytes.

config BR2_TARGET_ROOTFS_BTRFS_SIZE_SECTOR
	string "sector size"
	default "4096"
	help
	  This value should be set to the page size in bytes. The
	  default value of 4096 is the the most common page size for
	  most systems.  If the sectorsize differs from the page size,
	  the created filesystem may not be mountable by the kernel.
	  Therefore it is recommended to leave this value at
	  4096. Unless you know that your kernel uses a different page
	  size.  Suffix with k for power-of-two kilobytes.

config BR2_TARGET_ROOTFS_BTRFS_SIZE_NODE
	string "btree node size"
	default "16384"
	help
	  The tree block size in which btrfs stores metadata in bytes.
	  This must be a multiple of the sectorsize, but not larger
	  than 64KiB (65536).
	  Suffix with k for power-of-two kilobytes.

config BR2_TARGET_ROOTFS_BTRFS_FEATURES
	string "Filesystem Features"
	help
	  A comma separated string of features that can be enabled
	  during creation time.
