@poddingue Thanks for running the -31 numbers — good to have it confirmed that the ttyS0 removal stays worth ~3-4s even with the clock fixed. Agreed on not rushing -proposed to production; we'll pick up -31 when it promotes and keep the cloud-init tweak permanently.

@furyflash777 I'm assuming you're on Ubuntu? Indeed as Olivier said this is tested on Debian and doesn't cause issues, but it seems on the newer Ubuntu versions with cloud-init, the new Netplan based network manager and how it interacts with cloud-init breaks/gets wiped if no cloud-init drive is found. Yet another cloud-init bug to track down
