+Conclusions:
   * It is related to build on ZFS. In this case LXC on Proxmox's LXC.
   * It works before.
   * It works for another (bigger) image.
+  * It is related to ''wic'' image.
+  * Yocto's ''image.bbclass'' was fixed to correctly calculate sizes on compressed ZFS:
+    * Problem raised here: [[https://lists.yoctoproject.org/g/poky/topic/image_bbclass/81548542|image.bbclass - get_rootfs_size]]
+    * And fixed here:
+      * [[https://git.yoctoproject.org/poky/commit/?h=master-next&id=3743234dab23e4068e1d1fde9e1fa0bc09fdb182|lib/oe/utils: add directory size function]]
+      * [[https://git.yoctoproject.org/poky/commit/?h=master-next&id=f7ed81182c7797fd6b0069fa5c90535b13848657|classes/image: use oe.utils.directory_size() instead of du]]
+  * Problem still exists in [[https://git.yoctoproject.org/poky/tree/scripts/lib/wic/partition.py#n279|poky/scripts/lib/wic/partition.py]]
+    * Task ''do_image_wic''.
+    * ''du'' returns real disc usage (135649) (on compressed ZFS) instead of data size (250920).
+    * adding ''--apparent-size'' fixes the issue (''du_cmd = "du -bks %s --apparent-size" % rootfs_dir'')
+    * Bug filled [[https://bugzilla.yoctoproject.org/show_bug.cgi?id=15951]]
