HI Brent, There are currently 6 DHCP related patches specifically to the client code. We have already determined that 2 of those patches the NSUPDATE protection could be removed, 2 seem to be StarlingX spceific but replaced with a enter-hook scripts provided in another patch. 1 is a backport dhclient-disable-NSUPDATE.patch support-disable-nsupdate.patch - Remove these 2 dhclient-handle-wrs-install-uuid.patch dhclient-dhcp6-wrs-install-uuid.patch - Can these be removed as the functionality is now added via the dhclient-enter-hooks script? dhclient-ipv6-bind-to-interface.patch - This is a backport, which will be available when CentOS updates to the newer version. dhclient-ipv6-conditionally-set-hostname.patch - Can this be moved to the dhclient-enter-hooks? dhclient-restrict-interfaces-to-command-line.patch - This seems to be adding functionality, in order to restrict the dhclient to only be active on one interface. There is no commit message for this one, or is there a way to refactor this? Is this a bug in dhclient? Was it ever filled or commented on in the DHCP mailing list? Thanks Sau!
