config BR2_TARGET_ROOTFS_BTRFS bool "btrfs root filesystem" select BR2_PACKAGE_HOST_BTRFS_PROGS help Build a btrfs root filesystem. If you enable this option, you probably want to enable the btrfs-progs package too. if BR2_TARGET_ROOTFS_BTRFS config BR2_TARGET_ROOTFS_BTRFS_LABEL 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.
