We're talking about different things here, I guess. For me if target
rootfs content in the image is different from rootfs produced by bitbake
it means it's modified.

BTW, if this patchset is accepted wic will not be changing fstab in original rootfs anymore:

However, it would not mean that rootfs is not changed.
