The backing files are limited to 4G because FAT because UEFI. Another option is btrfs seeding. https://btrfs.wiki.kernel.org/index.php/Seed-device The seed is read only. Sprout is read-write, for persistence. All changes go to the sprout. A reset means wiping the sprout. Removing the seed device results in replication, i.e. seed is copied to the sprout. Copy is at the block group level, so compressed extents are not decompressed. Makes for faster replication. -- Chris Murphy >
