Well, bummer, if after all it works for the services.  How to give
better feedback to the admin, or convenience through tools that
add/remove, enable/disable services plus dependencies, just requires
some better organization of the dependency information.

You can easily tell runit about this special dependency, add 'sv term
postfix' to the ./finish script of postgrey, if you really want postfix
to be disabled while postgrey crashes.
