Given a system administrator configures a RHEL-9.5 system with NetworkManager, When they attempt to set up a DHCP for network interfaces using dhclient, Then, NetworkManager should warn the user about its deprecation. Definition of Done: The implementation meets the acceptance criteria Unit test and integration test are written and pass The fix is part of a downstream build attached to an errata The initial text for this enhancement in the feature-reason-result format (More details  here ) An entry to the NEWS file is added mentioning the deprecation Mention in the NetworkManager.conf man page the deprecation Add a warning when dhclient is enabled during the build Log a warning when NetworkManager starts with dhclient configured

.The `dhcp-client` package is deprecated Previously, you could configure NetworkManager in RHEL 9 to use a DHCP client from the `dhcp-client` package. However, the option to use the `dhclient` utility is now deprecated and results in a warning being displayed at the NetworkManager startup. To configure NetworkManager as described above, switch to the internal DHCP library. In RHEL 10, the `dhcp-client` package is no longer available and the applications configured to use the `dhclient` utility use the internal DHCP library instead.
