It appears that I cannot undo the damege in posting because it is called after dpkg compares configs. So I migrated checking to preinst, where I check if the upgraded version in 1.4.X and reverse the damage. However this breaks the upgrade in postinst, in which debhelper injects code to start/stop maradns. It cannot stop previous maradns because the config in different (different user and group). Is it ok to manually kill process in preinst in such situation ? -- Pozdrawiam, Dariusz Dwornikowski, Assistant at Institute of Computing Science, Poznań University of Technology www.cs.put.poznan.pl/ddwornikowski/ room 2.7.2 BTiCW | tel. +48 61 665 29 41
