Just upgraded to Fedora 17 and discovered that webmin is no longer able to start/stop apache from the Apache module. I get the message
sh: /etc/rc.d/init.d/httpd: No such file or directory
It is possible to start/stop through the bootup/shutdown section. I'm not a Linux expert but it looks to me that the mechanism for starting services has completely changed in Fedora 17
Perhaps obvious, but this issue applies to starting stopping other modules such as mysqld as well.
