My thinking was a bit different. I had in mind a setup where the "ext4"
format as used by qemu has all files of the rootfs in a single
partition, whereas the wic image splits out the data into multiple
partitions (it recently gained such a feature).

This could be made to work if wic knew how to change fstab without
rewriting the root filesystem. But as that can't be done, such a
combination of different image formats is only possible for a rootfs
which always works with just a single partition.
