There is a dependency type that sounds just like the job for this
situation: exclude_all. The dependency is satisfied when !{service},
man smf(5) for more. Never seen this used, so not sure what the framers
intended.
The problematic thing I see is that the dependency is on service, and
you are working with instances. Unless you do have properties that are
inherited from service to instance, is it possible to make sendmail,
postfix, qmail, exim all different *services*, instead of smtp:instance?
Just my thoughts on a hack, would love to hear how you make out after
you're done.
