Thank you for your report. This bug is better filed against netplan in the first instance, so the netplan developers can consider your use case.
If I were you, I'd expand on your use case, explaining what you're doing and why you need it and so forth, if you want anything addressed before Bionic's release. Note though that according to https://wiki.ubuntu.com/Netplan using ifupdown is still an option - you just need to request that explicitly at install time (or switch later). ** Package changed: systemd (Ubuntu) => nplan (Ubuntu) ** Summary changed: - systemd-networkd supports neither MAC address DHCP nor SendHostname - DO NOT RELEASE BIONIC WITHOUT CHANGING BACK TO dhclient PLEASE PLEASE PLEASE (or else configure netplan to use these options properly) + netplan's networkd renderer supports neither MAC address DHCP nor SendHostname -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to systemd in Ubuntu. https://bugs.launchpad.net/bugs/1752142 Title: netplan's networkd renderer supports neither MAC address DHCP nor SendHostname Status in nplan package in Ubuntu: New Bug description: The default behavior with netplan is dramatically different from dhclient. You are going to cause a lot of headaches if you don't change it to use MAC addresses and SendHostname by default -- or at least give us a way to configure this behavior in Netplan.
