If I read the triggers documentation correctly, the situation is a bit different (please correct my, if I'm wrong. I just quickly glanced at triggers.txt) update-icon-caches/update-desktop-database would have to be made triggers-aware and install a triggers control file (e.g. interest /usr/share/icons or interest /usr/share/applications ) A package installing icons or a desktop file, would remove all calls to dh_desktop/dh_icons (that's why cdbs kde.mk/gnome.mk would have to be updated to remove the dh_desktop/dh_icons calls). The triggers would be activated by installing files into the above directories. An alternative would be, to keep dh_desktop/dh_icons around, to provide backwards compatibility (if triggers-aware dpkg is installed, they would be simple no-ops, otherwise they would behave as before). Cheers, Michael  Will changes to subdirectories (e.g /usr/share/applications/kde) also lead to a trigger, or would one have to register all subdirectories recursively? -- Why is it that all of the instruments seeking intelligent life in the universe are pointed away from Earth?
