From: Charles-Antoine Couret <[email protected]> If defined, this variable value overrides the size of btrfs partition file created by mkfs. Otherwise previous logic based on ROOTFS_SIZE variable is used.
It should be set when the final file size would not be above a specific value due to fixed partitionning for example.
