I will do it, but it will have to wait for weekend after next since I have
to
go the SIAM CSE.

We solve equations in a high-aspect ratio domain and have both a 2- and
3-dimensional DA which need to be compatible. Due to the nature of the
problem, the x-direction of the 3D DA must be local which means that
options such as -da_processors_x don't work (they mean different things
for each DA, thus forcing an incompatible state).
It is currently not possible to set an options prefix on a DA because
the usual PETSc creation pattern isn't used. A hack that would fix my
problem is to just add a prefix argument to DACreate, but the more
elegant solution is a more significant refactoring to DACreate,
DASetSizes, DASetOptionsPrefix, DASetFromOptions.
