You could make the config.d filenames insignificant and just keep them
as convention.


    <dll import="libfoo" target="libfoo.so" version="2"/>


    <dll import="libfoo" target="libfoo.so" version="1"

So each app could add/control/whatever any files it needed for its
purposes without conflicting with files from other packages.  Granted,
there is a chance for filename conflicts, but no more of a chance than
anywhere else in the *nix world.

I don't know how the currently config file loading/scanning works, so
I'm not sure if this would push any sort of performance loss considering
you could not just scan for conf.d/the-library-Im-looking-for.xml but
would instead have to check for conf.d/* (I'd assume not, I mean they're
just 3 line text files after all)
