Package: apache2 Version: 2.4.25-3+deb9u3 Severity: normal Dear Maintainer,
"apache2ctl start" disables a perl cgi script to read the content of /var/tmp, whereas "apache2ctl graceful" after "apache2ctl stop" (the stop is necessary) does not. There are other symptoms, probably related to bug 879571: OK: apache2 -h Usage: apache2 [-D name] [-d directory] [-f file] ...
