What gives the best results is if lightdm can parse this itself. Otherwise
you have the problem of various files in /etc, some of which are
authoritative and can be edited, some of which aren't and will be
overwritten.

As long as there's a well-defined lexicographical order in which the files
are read, and a consistent policy of which key wins (first instance wins vs.
last instance wins), I don't think it's a problem.

Well, presumably all possible combinations of keys should be valid from
lightdm's POV, otherwise the keys should be consolidated. :) This feels to
me like a problem that can be punted over to any such packages that are
requesting contradictory settings, to let them figure it out amongst
themselves.
