Hi @vittyvk, thank you for opening this. It's in our backlog to review+test |

references #2640 |
RHEL8+ uses NetworkManager and the most recent RHEL10 switched to using built-in dhcp client making DefaultOSUtil.set_dhcp_hostname() unsuitable. In fact, RHEL distos had been carrying RHEL-only downstream patch replacing RedhatOSModernUtil.set_dhcp_hostname() with nmcli device modify <DEV> ipv4.dhcp-hostname <HOSTNAME ipv6.dhcp-hostname <HOSTNAME> since RHEL8 but this is also not ideal as 'nmcli device modify' does not persist the change. Complement this with 'nmcli connection modify' to both make the immediate change and persist it. Signed-off-by: Vitaly Kuznetsov <vkuznets@redhat.com>

While this is still on review, I added a simple re-try mechanism for 'nmcli device modify' as it was found that this action can coincide with NetworkManager's interface re-configuration. |
