Package: piuparts Version: 0.62 Severity: wishlist https://bugs.debian.org/809744 /var/lib/dpkg/info/udev.prerm called with unknown argument 'deconfigure'
This something piuparts could check for (as well as all the other ways to call a maintainer script (if a package is installed)). iirc dpkg has no possibility to explicitly deconfigure a package. Andreas
