Bug Description
Before populating the partitions during a classic image build, ubuntu-image calculates the rootfs size by calling `du -s -B1`. On ZFS, this might return a compressed size, and thus not the real size of the directory once written to another FS (in our case for example ext4).
To fix this, I see several solutions:
- recursively walk the rootfs directory with filepath.Walk and sum everything
- use the `--apparent-size` flag of du
