[Bug 2096762] Re: Please update to 20250107.00

Copying catred's comment here for completeness [0]

> This SRU creates a regression in cloud-init behaviour.

  Using the following user_data hostname.yaml:
  #cloud-config
  manage_etc_hosts: true
  hostname: cloudinit1
  fqdn: cloudinit2.i9n.cloud-init.io
  create_hostname_file: true

  On an existing noble image:
  $ gcloud compute instances create hostname-noble --image-project ubuntu-os-cloud --image ubuntu-2404-
  noble-amd64-v20250313 --metadata-from-file user-data=hostname.yaml
  [...]
  catred at cloudinit1:~$ hostname
  cloudinit1
  catred at cloudinit1:~$ hostname -f
  cloudinit2.i9n.cloud-init.io

  With the proposed package changes:
  $ gcloud compute instances create hostname-noble-sru --image-project ubuntu-os-cloud-image-proposed --
  image testing-ubuntu-guest-2404-noble-amd64-v20250218 --metadata-from-file user-data=hostname.yaml
  [...]
  catred at hostname-noble-sru:~$ hostname
  hostname-noble-sru
  catred at hostname-noble-sru:~$ hostname -f
  hostname-noble-sru.c.ubuntu-catred.internal

  A user attempting to set their hostname via cloud-init will no longer get their expected behaviour, but
  will get the hostname set as the internal default Google hostname. For any user using cloud-init to
  manage a large fleet of servers this could be a breaking change.

Bug description:
  ===== SRU =====

  Following on from similar package update requests @ LP: #2084486, LP:
  #2073164, LP: #2066314 and LP: #2033061, this bug is a request to
  update gce-compute-image-packages to the upstream version
  `20250107.00` @ https://github.com/GoogleCloudPlatform/guest-
  configs/releases/tag/20250107.00

  This package has an SRU exception @
  https://wiki.ubuntu.com/StableReleaseUpdates#gce-compute-image-
  packages including an ageing exception detailed @
  https://wiki.ubuntu.com/gce-compute-image-packages-Updates

  [Impact]

  This package is provided by Google for installation within guests that
  run on Google Compute Engine. It is part of a collection of tools and
  daemons, that ensure that the Ubuntu images published to GCE run
  properly on their platform.

  Cloud platforms evolve at a rate that can't be handled in six-month
  increments, and they will often develop features that they would like
  to be available to customers who don't want to upgrade from earlier
  Ubuntu releases. As such, updating this package to more recent
  upstream releases is required within all Ubuntu releases, so they
  continue to function properly in the GCP environment.

  [Test Case]

  When a new version of this package is uploaded to -proposed, the
  following will happen:

   * an image based on -proposed will be built for GCE and published to the ubuntu-os-cloud-image-proposed project
   * the CPC team will run internal validations (CTF) and Google's upstream test suite `cloud-image-tests` (CIT)
   * the GCE team will be asked to validate that the new package addresses the issues it is expected to address, and that the image passes their own internal image validation.

  If all the testing indicates that the new package is acceptable,
  verification can be considered done.

  [Vendored Dependencies]

  N/A for gce-compute-image-packages

  [Where Problems Could Occur]

  There are many upstream changes in `20250107.00-0ubuntu1` vs.
  `20241010.00-0ubuntu1`;however between the cloud-image-tests suite [0]
  (which is run for validation by CPC _and_ Google) and CPC's own
  internal test harness (CTF), there is confidence that most if not all
  "edge cases" and/or obvious regressions concerns can be dismissed
  before the new version lands in `-updates`.

  [Other Information]

  This bug is used for tracking of releasing the new upstream version
  for all supported series, as per the approved policy mentioned in the
  following MRE:

  https://wiki.ubuntu.com/gce-compute-image-packages-Updates

  This package is only used for AMD64 and ARM64 but is built for all
  available architectures.
