Now that we have the cloud-minimal seed for minimized cloud
image builds, we should drop all the workarounds and hacks
we once needed when we were using the server seed. We can
directly use the new metapackage and get rid of the tasks and
other autoremoves, et al.
Package linux-allwinner has a kernel with the generic flavour as

Remove kvm-image altogether.
Previously for minimal image replace_kernel function replaced virtual
images with kvm, and called force_boot_without_initramfs. Now simply
call force_boot_without_initramfs for minimal image without replacing
kernel flavour.
This also means minimal images can now be built for arm64 and armhf.

Up to now we have used u-boot-menu for preinstalled images for the SiFive
HiFive Unmatched and Unleashed boards and GRUB for all other RISC-V images.
The choice was made because RISC-V GRUB was not available when the SiFive
boards where released.
Let the Unmatched and Unleashed board preinstalled images use GRUB.
Simplify the code.

Canonical Public Cloud's project seems a bad place to build images for
hardware devices however this is how things were done a we now need to
maintain this.
The recent change to mount the ESP on /boot breaks those images, instead
of adding more hacky things in the hook, create a dedicated target for
those images and use a different hook to build UEFI images.
This is required by the new UEFI binary hook as we mount the ESP on
/boot and the ESP filesystem doesn't support symlinks.
We keep symlinks for s390x images which do not use UEFI anyway.
This is driven by online encryption scenarios. In order to efficiently
encrypt the root filesystem without modifying the partition layout, the
kernel should sit in an un-encrypted /boot partition. Instead of
creating a new partition that would change the default partition layout,
we mount the ESP on /boot. We also need to then bind mount /boot on
/boot/efi because that's where Grub expects the ESP to be located.
This now matches the cloud images (7c760864fd)
fixing bootloader updates in the buildd images, but also fixing
compatibility with using devtmpfs for losetup.
kpartx on riscv64 appears to be racy. Rather than trying to debug these
fraught races somewhere between udev and libdevmapper, we can use losetup
which should be simpler and less error-prone.
live-build/auto/config:
- for Ubuntu Server live images and the arm64+tegra full arch, build a
tegra variant with linux-nvidia-tegra as the flavor and
linux-nvidia-tegra as the kernel meta-package
- default to nvidia-$SUBARCH as the kernel flavor for all images using
arm64+tegra as full arch
hooks/03-kernel-metapkg.chroot_early:
- use linux-nvidia-tegra as kernel meta-package for the nvidia-tegra
flavor
missing a && between icicle and visionfive, led to /boot/efi still being
in place, and grub-install running instead of exiting the func.

Cloud-init cannot write directly to
/etc/NetworkManager/system-connections because subiquity may
need to emit config to /etc/netplan/00-installer.yaml and call
netplan apply for autoinstall.network use-cases.
When cloud-init's config is written directly to
/etc/NetworkManager, neither netplan nor subiquity has knowledge of
this config and this results in namespace collisions in NetworkManager
due to `netplan-` named connections and `cloud-init` connection ids
fighting over which config own a given interface name.
Deleting this config overlay allows subiquity to manage all network
setup when it needs to with netplan directly.
Subiquity already has logic to rename any unwanted netplan
configuration when it intends to write cfg and run netplan apply[1].
This should allow subiquity full control of network config when needed.

Autoinstall directives can be provided on the grub cmdline to
cloud-init via kernel parameters like the following:
autoinstall 'ds=nocloud-net;s=http://somedomain/'
In order to support DNS resolution for NoCloud datasource at
datasource discovery time, cloud-init.service needs to be
orderered after NetworkManager.service and
NetworkManager-wait-online.service
which will have brought up applicable NICs.
Since NetworkManager is After=dbus.service, the cloud-init.service
avoids systemd ordering cycles by also dropping
Before=sysinit.target when it adds, After=NetworkManager.service and
After=NetworkManager-wait-online.service
Add this file overlay for /lib/systemd/system/cloud-init.service
because systemd drop-in files can only add constraints and not
drop prexisting service constraints.
Also add an AUTOMATION_HEADER comment to any generated files to
add discoverability in the event of future bugs/concerns.

ipc was dropped as an apparmor feature. checked by grabbing the latest
lunar VM, installing the latest kernel, doing a reboot, and comparing
directories and files. compared all files and the only diff is the ipc
posix_mqueue
Evolve the seed to only ship the specific part useful to WSL users. This
allows to trim down the image size.
