Hey. I've recently noted that my systems have files in /var/lib/dpkg/triggers, which are no longer there on fresh installations.
For example: /var/lib/dpkg/triggers/resolvconf-event /var/lib/dpkg/triggers/rkhunter-update-database which seem to have been previously used by their respective packages (before being renamed) and are now empty. Not sure if /var/lib/dpkg/triggers/Unincorp is another leftover (at least it's empty). Shouldn't packages clean up old triggers like /var/lib/dpkg/triggers/resolvconf-event? Thanks, Chris.
