***********************************************
I confirm that neutron-server version 2:24.1.0-0ubuntu1.1 from noble-
proposed fixes LP: #2126923 on Noble (LTS). Verified by reproducing the
failure with multiple values in ovn_dhcp4_global_options on
2:24.1.0-0ubuntu1, then confirming neutron-server starts successfully
with the same configuration after upgrading to 2:24.1.0-0ubuntu1.1.
