I'm thinking more in a different direction: change find-provides
that it generates a "Provide: trigger:gtk_update_icon_cache" and
add a trigger to the package containing gtk-update-icon-cache.
The trigger should get the hdrid of the triggering package as
argument, so that it can query the file list (rpm --querybynumber).
It then can do it's magic with the matching files.

My main goal is to get rid of most of the scriptlets, as packages
tend to scrw up writing them. There could be a "trigger:useradd = foo"
trigger, or a "trigger:service" trigger for /etc/init.d/ services.
Dunno if it's really doable, though.

Cheers,
  Michael.
