The location of the linuxconf binary has been moved to /sbin. But the /etc/rc.d/init.d/network script has not been modified. This make the "network probe" silently fail. If a user change a network configuration, normally, linuxconf will report that a "network reload" is required. With this bug, linuxconf will never report anything. The bug affect also the "status" command (/etc/rc.d/init.d/network status) which won't report much useful information.
It will be fixed in 5.50-1.
