If we choose a linear TS solver, shouldn't it set the type to LINEAR, and likewise for nonlinear? Then a user could query this for information. We want to do just that in PyLith.
Is your concern that many of the examples never bother to set the type? Or that not enough error checking is done that the set type works with solution method selected by the user? I think these are just oversights and you should go ahead and add these in the examples and code where appropriate.
