Checkmk Werk 13121: Linux agent: Produce <tt>ntp</tt> section on additional systems (eg. Slackware)

ID: 13121 Title: Linux agent: Produce <tt>ntp</tt> section on additional systems (eg. Slackware) Component: Checks & agents Level: 1 Class: Bug fix Version: 2.1.0i1 Before producing the <tt>ntp</tt> section, the linux agent checks if a corresponding <tt>systemd<tt> service or a deamon under <tt>/etc/init.d/</tt> exits. Hence, on systems without <tt>systemd<tt> and <tt>init.d</tt>, such as Slackware, the <tt>ntp</tt> section was never produced. The agent now additionally checks if <tt>/etc/rc.d/rc.ntpd</tt> is found and executable. This re-enables the <tt>ntp</tt> section for example for Slackware.
