Ah, ooops!

Basically: that error makes sense (to us programmers), because
the constraint is: "there is no way to do this" (NULL).

So, what should ped_file_system_get_create_constraint() return if
there's no implementation for that fs?  Should the front-end
check if it's NULL, and deduce there's no support for that FS?

This is a big problem in general with constraint solvers: they
are good at finding solutions, but bad at explaining why solutions
don't exist.

Ideas?

Andrew
