For Ubuntu 24.04 and later cloud-init is included in desktop images. This is not applicable for Hyperv images so
we can disable cloud-init. This leaves the cloud-init package installed but disabled so users can still
use it if they want.
This is a documented way to disable cloud-init. See https://cloudinit.readthedocs.io/en/latest/howto/disable_cloud_init.html
A change in 8fb21808 also removed many of the dependencies that the hyperv images require.
This removal has been restored in this commit by adding them expliciltly in the hyperv hook.
We have not built Hyperv desktop images since Jammy and with the re-introduction of HyperV for Noble we have encountered build issues caused by refactoring and removals of code assumed to be redundant but the HyperV desktop images were actually using these code paths.
In bbedffe6 we split the building of cloud images and non cloud to using an ddisk-image-uefi.binary and disk-image-uefi-non-cloud.binary respectively. In e38264ca there was a change which meant that any attempt to build hyperv images would result in incorrect disk size and incorrect disk label.
This has been fixed by ensuring that the ubuntu:desktop-preinstalled $PROJECT:$SUBPROJECT matches and sets the correct disk size and correct disk label.
A change in 76d79466 changed the logic of how the image size for amd64 images were being set. This overrode the sizes set for the desktop images incorrectly.
This commit ensures that any desktop image being created uses the correct image size.
do_layered_desktop_image() is now the standard entry point for flavors using
ubuntu-desktop-bootstrap and handles minimal/standard/live layers in a
configurable and flavor-agnostic way to reduce code duplication.
Failing CPC tests show that the preseeded apparmor features don't
include policy:unconfined_restrictions for the 6.8 kernel. This
change adds the feature preseed with values based on a successfully
booted instance.

ubuntu/include.* are the master location for these files.
Copy them over for projects with similar needs, while skipping ones that
are incorrect.
LP: #2055077
Ubuntu MATE is switching to a layered image in preparation to
use ubuntu-desktop-provision. Luckily, their seed structure is
already well-structured for layering, so this is easily done.
This has become moot now that the code block has been
moved out from live-build/functions to live-build/auto/build
so passing the argument is not needed anymore.
Presence of this field helps in determining if the image is an
unminimized image, which then can be leveraged in the unminimize
script to easily determine the image type.
As part of addressing LP: #2054103 [1] an update to grub-pc added a feature to be able to ensure that grub-pc
installation can happen noninteractively on cloud images.
This change is equivalent to running
```
debconf-set-selections grub-pc grub-efi/cloud_style_installation boolean true
debconf-set-selections grub-pc grub-pc/cloud_style_installation boolean true
```
These were introduced optionally to determine the install device using
`grub-probe` dynamically instead of having to fill the `grub-pc/install-devices`
debconf entry.
