groovy hangs during boot on ESXi when the version is greater than
10. Adding a serial port by default fixes this specific bug - increasing
the HW version will be for another branch.
This is because more investigation is needed into whether it is possible to
increment ddb.virtualHWVersion without disrupting Oracle VirtualBox images.
armhf & arm64 images use grub. And despite disk-image &
disk-image-uefi installing all the grubs, some of the configuration is
done in the 999-cpc-fixes. Specifically removal of "quiet splash" is
done there, but not active on armhf & arm64. This results in arm
images to boot with "quiet splash".
Enable running the later portions of 999-cpc-fixes on armhf & arm64.
Drop duplicate call to update-grub, as update-grub2 is simply a
symlink to update-grub.
Add a guard around the call to reconfigure grub-pc, to only do that
when it is installed.
This makes armhf & arm64 uefi images consistent with amd64 uefi
images.

The case is for arch:subarch combo, not just arch alone even if
subarch is empty. Thus currently on adm64/arm64/armhf ubuntu-cpc
builds mbr image is created and then ignored, as the convert to qcow2
hook prefers the uefi image whenever available.
Skipping building these correctly, should speed up the build a little
bit and use slightly less disk space.
shim-signed depends on grub-efi-amd64-signed, which in turn has
alternative depends on either `grub-efi-amd64 | grub-pc`. However to
support booting with either via shim&signed-grub and BIOS, the choice
must be made to install grub-pc, not grub-efi-amd64.
This makes images consistent with Ubuntu Deskop, Live Server, buildd
bootable images; all of which already do install grub-pc and
shim-signed.
LP: #1901906
The CPC build hooks for amd64 incorrectly attempt to install shim-signed
in addition to grub-efi-amd64 and grub-pc. These latter two packages
conflict with each other. Instead shim-signed should install whatever
packages are required.
Additionally, this will ensure that autoremove is run after installing
anything in the CPC build hooks. This is done to avoid shipping images
that include packages that are autoremovable. This will clean-up as
packages are installed and detect any breakage at build time.
virtualbox-guest-utils kernel modules is included in linux-modules
starting in kernel 5.4.0-33 in focal-updates. The vagrant hook also
explicit installed virtualbox-guest-utils. An error occurred with the
version installed from the archives, however, with the inclusion in
linux-modules, there's no need to explicitly install
virtualbox-guest-utils. Removes the code for the explicit install.
