This error is not related with the issue (now fixed) that made me look at the zypp log in the first place. I reported it only because it seems strange (to me) that (apparently) every update of the apache2 package runs it again. I understand that if the modules to be removed are not there there's 'nothing to do', but that script also enables some modules (authn_core, authz_core, log_config) and that may alter an otherwise working configuration. My logged-in root user has the following: PATH=/sbin:/usr/sbin:/usr/local/sbin:/root/bin:/usr/local/bin:/usr/bin:/bin:/usr/bin/X11:/usr/games:/opt/bin:/opt/kde3/bin
