  That would mean that if the verion of package A changes, only A and
its direct dependencies are rebuilt, but indirect dependencies are
not?

  Joerg: could you please add an option so this can be selected via
config file?  I think it's a valuable option to have.

  Everyone: do we feel this is an acceptable tradeof for our official
