I think that normally, companies define certain quality goals and use Hudson's
plugins to achieve them. However, defining the same configuration over and over
again for every job is something that IMHO needs to be fixed.
One possible solution would be a "master" job which is configured once. All
dependent jobs can then override any configuration, if they want to.
As far as I can see (being new to Hudson), this has been requested on the
mailing list before, but I didn't find any enhancement request in here.
