Bug description:
  Hi there, noticed a thing when setting up a Raspberry Pi 4 (CM4) with
  an ubuntu 22.04.1 server image, but I suspect it might affect more.

  I used this how-to:

  https://ubuntu.com/tutorials/how-to-install-ubuntu-on-your-raspberry-
  pi#1-overview

  and it worked the second time. :) Sort of.

  The module is a Raspberry Pi Compute Module 4 Rev 1.1, CM4002016, no
  WLAN, 2GB RAM, 16GB eMMC drive. Omitting the WLAN settings when
  writing the image with the Pi Imager helped, otherwise the module
  won't be reachable by network, even if there is a cable on eth0 or via
  USB eth adapter. That as an aside.

  Now to the real issue: Giving all the data includes hostname, user /
  pass, ssh key. They will be set up correctly. However, when the module
  boots up the first time with the new image and cloud-init does its
  thing, it announces itself as hostname "ubuntu" to the DHCP server.
  Okay, why not, but why? Later on (20 minutes later, after completing
  sudo apt-get update and sudo apt-get dist-upgrade, and restarting of
  affected services) it correctly announces and registers with the
  desired hostname.

  This is a bit odd, and given that the right hostname was available, I
  would suspect some order of execution issue.
