If build happens on zfs filesystem with compression enabled,
then image size calculations in do_image_wic task can fail:
output: mke2fs 1.47.0 (5-Feb-2023)
Discarding device blocks: done
Creating filesystem with 351999 4k blocks and 176000 inodes

system
du --help says:
--apparent-size print apparent sizes, rather than disk usage; although
the apparent size is usually smaller, it may be
larger due to holes in ('sparse') files, internal
fragmentation, indirect blocks, and the like
du -b already includes --apparent-size.
Same issue reported also in https://lists.yoctoproject.org/g/poky/message/12389
