Martin Wilck, I am afraid I do not know why hplip is built with --disable-policykit. Usually I provide a comment in hplip.spec when I specify non-default configure options but there is nothing about --disable-policykit. Only a blind guess because in hplip.changes I found ---------------------------------------------------------------------------- Tue May 5 14:54:42 CEST 2009 - jsmeix@suse.de ... - Updated to version 3.9.4: Added PolicyKit support. Command line tools like hp-setup, hp-plugin, etc. are now run as regular user. ---------------------------------------------------------------------------- I guess --disable-policykit might have beed added at that time or some time later but I cannot remember the reason why.
