I think it could be possible to write it as well, but only deep > inside the rpm (when rpm evaluates possible conflicts in forthcoming > transaction). it should not be very hard to have pretrans filetriggers, but it would be dangerous if the transaction somehow fails. eg: the gconf schema gets uninstalled in %prettrans, but a rollback re-adding it would be necessary on failure. And even if rollback was handled nicely, it would imply some unnecessary uninstall of schema (since the install will handle existing schema). A solution could be: files needing subscription/unsubscription could be renamed to .rpmprevious instead of being removed ; then used in filetrigger, and only removed what all this is done. Still, the filetrigger script would need to be able to check the difference between previous and new file, to know what to do, which may not be easy... _______________________________________________ Rpm-maint mailing list Rpm-maint@lists.rpm.org https://lists.rpm.org/mailman/listinfo/rpm-maint
