Comment # 5 on bug 1190567 from Michal Suchanek

This is not exactly new.

You can have an EFI boot partition on the target system, and if you do an image
on a system without one then you don't have any content to copy there.

By making an image on some system and copying it to a different system you
*can* break things.

You could also call it backwards that you make an image on a system that has
one partition layout and expect it to work with different partition layout.

Like you could make an image on btrfs that has snapper configured and then you
deploy it on xfs and suddenly the snapper services fail.

We actually do have a kernel post script that you can call now but I am not
sure we want to make it a stable enough public API that anyone can use
