On (automatic) agent update on Linux, the update process includes the reload of the xinetd process, if running. This is done by the DEB maintainer scripts or RPM scriptlets, respectively.

There are some rare situations (e.g., LCX containers with a running xinetd) that lead to a falsely detected xinetd process on the host system. In that case, the update process would crash on trying to reload xinetd.

This behavior is mitigated with this werk, by only detecting running xinetd processes that run under root (uid 0).
