To clarify: - I'm now running version `237-3ubuntu10.41` of both `systemd` and `libsystemd0`. - With the DHCP MTU option removed, the network interface comes up correctly and remains stable.

After updating the `systemd` package past `237-3ubuntu10.32`, I see the onboard NIC link being taken down / up repeatedly, as shown below (dates are from my original notes, but the issue remains the same today). The NIC fails to remain up, and all networking is out of action. Running `systemctl stop systemd-netword` stops this and leaves the NIC in an unknown state. Subsequently running `ifconfig eno1 up && dhclient eno1` allows networking to continue basic operation, albeit without systemd's oversight. My original solution was to downgrade both the `libsystemd0` and `systemd` packages to `237-3ubuntu10.28`. After attempting an `apt update && apt upgrade` again today, exactly the same thing is happening with `237-3ubuntu10.41`.
