I can confirm this behavior in on Ubuntu 24.04.3 LTS. I did a wireshark session during bootup:
- dhcpcd in initrd sends dhcpv4-requests without option 61 (client identifier) - network-manager later on sends dhcpv4-requests with option 61 (client identifier) - length7, hardware type: ethernet Unfortunately the workaround described in #5 did not work for me. replacing "duid ll" by "clientid" in /usr/share/initramfs- tools/hooks/dhcpcd and running `update-initramfs -u` does not change the requests, beeing sent by dhcpcd. They still contain no client identifier option. Network-Initrd-Config, was done by echo IP=::::myhostname:eno1:dhcp > /etc/initramfs-tools/conf.d/hostname -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2109847 Title: initramfs DHCP uses inconsistent client IDs To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/initramfs-tools/+bug/2109847/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
