> ParMETIS is our current default partitioner in parallel runs Are you calling Parmetis via a `PetscExternalPartitioner`? If so then I'd not call that a "default"; it's something that has...

IIRC several years ago we put basic remapping into libMesh::System I/O: variable data would be read into variables of the same name regardless of whether the variable ordering/numbering had changed,...

Closing this in favor of a much bigger branch with diagnostics and fixes for the bugs I uncovered.
