Novell ZENworks Configuration Management 11 Installation - Agent
ZCM un-installer removes xinetd package.
This is fixed in version 11.2.1 - see KB 7010042 "ZENworks Configuration Management 11.2.1 - update information and list of fixes" which can be found at https://support.microfocus.com/kb/doc.php?id=7010042
ZCM agent keeps track of installed rpms in AgentInstallConfig.xml, which is also used by the uninstaller to determine which rpms have to be un-installed. One of the rpms installed/updated by ZCM is 'xinetd', and case the un-installer is executed, it will remove that package from the system.
