Core and Extras maintainers coordination

[Nathan Grennan]

  I think coordination between core and extras maintainers needs to
increase if extras isn't to be second class.

  Yesterday a new update for Mozilla came out, 1.7.10. Galeon in extras
prevented the updates from being installed, because it hadn't been
recompiled. This is just one example of how things can break when
something in extras depends on a certain version of something in core. 

  Adding a dependency checking system to the build environment that
contains both core and extras packages would help detect the problems,
and help coordination. Realistically you can't just automatically
rebuild the dependencies in all cases. Hence some delay will have to be
added if core and extras are to stay in sync at all times. Giving the
extras maintainers notification and time to rebuild, or request a
rebuild before an update is released.
