How to deal with swap (btrfs does not support swap files)?
The partition size calculation is too naive for situations where experienced users use customize-image.sh to import few hundred GB of uncompressable data. A better approach would be to already use btrfs to create the tmpfs since then a ‘btrfs filesystem df’ could be used to calculate the size of an ext4 rootfs while we could use the compressed size 1:1 for creating partitions. On the other hand this use case is very special and experienced users could make use of a fixed image size in such situations
How to deal with snapshots? Creating an initial ‘release’ snapshot seems like a good idea to me. Also installing ‘apt-btrfs-snapshot’ on Xenial by default is worth a consideration IMO
I didn’t find the right solution from the Internet.
