emm...I see the new name servers are appended to the current name servers list. https://github.com/canonical/cloud- init/blob/master/cloudinit/distros/parsers/resolv_conf.py#L79
So the new name servers are always in the tail, if there are already 3 current name servers exist, then any new name servers will be discarded. In our scenario, new name servers sent to cloud-init by OVF datasource, but the result is inconsistent, depends on how many name servers exist before power-on. If change the implementation to append the current name servers to the new name servers, then the current name servers are in the tail, then keep the first 3 of the list. In such way, new name servers can be always set. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1892447 Title: Why ignore new name server if 3 name servers exists To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/cloud-init/+bug/1892447/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
