Yeah in this case if the conversion is done, I'd just recommend
installing filesystem --nodeps and the rest should flow. It's not ideal
certainly, but there is still time to polish this a bit before upgraders
get hit by this (and as there will be updated rpm packages in the stable
releases, it should mitigate this specific problem, but we should still
see if we can do things better)
