The xntpd daemon does not start and stop automatically
when the system run level changes, because the necessary
S??xntpd and K??xntpd links are not installed in the rc?.d
directories from the rpm package. It works fine if you
install the links by hand.
Use chkconfig and/or ntsysv to turn them on.
*** Bug 5777 has been marked as a duplicate of this bug. ***
Symbolic links in directories /etc/rc.d/rc3.d or rc5.d
to /etc/rc.d/init.d/xntpd are not installed initially.
The packages is missing such files.
