As of grub2 >= 2.02-95 on redhat family distros, calling grub2-install
on an EFI partition will fail with: "this utility cannot be used for
EFI platforms because it does not support UEFI Secure Boot."
This version of grub is now in centos8-stream and non-eus repos of
RHEL-8. It is not currently possible to build whole-disk UEFI images
on these distros, and when this package is promoted this will also
affect centos8 and RHEL-8 eus. The grub maintainers made this change
because the grub2-install generated /boot/efi/EFI/BOOT/BOOTX64.EFI
will never be capable of booting with Secure Boot.
This change defines a $EFI_BOOT_DIR for every distro element. When
directory /boot/efi/$EFI_BOOT_DIR exists a grub.cfg file in will be
generated there. This change also installs the shim package on redhat
family distros, which installs a copy of the shim bootloader to
/boot/efi/EFI/BOOT/BOOTX64.EFI. Using centos as an example, this
allows UEFI to boot the shim /boot/efi/EFI/BOOT/BOOTX64.EFI which
then chains to /boot/efi/EFI/centos/grubx64.efi.
If /boot/efi/$EFI_BOOT_DIR doesn't exist (such as for Ubuntu,
/boot/efi/EFI/ubuntu) the current behaviour of running grub-install to
generate /boot/efi/EFI/BOOT/BOOTX64.EFI will continue. For distros
such as Ubutnu where packaging does not populate /boot/efi/EFI/ubuntu
with .efi files, secure boot can be added in the future by copying
.efi files to /boot/efi/EFI/ubuntu and copying the shim file to
/boot/efi/EFI/BOOT/BOOTX64.EFI.

The current implementation evauates the dib-init-system
script too early. Also it looks that there is no simple
way of getting the info about the init system automatically:
another element can install (later on) a different
init system. Therefore the only reliable way of setting
this is manual.

The ubuntu-minimal README states that the latest Ubuntu LTS
is the default, but currently that is not true. This patch
changes the default to the current LTS.

The ubuntu, and ubuntu-minimal elements both make use of a common set
of environment settings to determine the distribution name.
The ubuntu-minimal element also does a few extra things which would
appear to apply to both sets and bring in extra architecture support.
As such, these are included in the common element.
This intends to be part of a series of patches which will eventually
create a new element to build a minimal ubuntu-systemd-container
element which can be used for lxc/nspawn containers.

Deploying many nodes with the generated image shouldn't have the same
/etc/machine-id so clearing it and letting systemd generate a new
id upon first boot seems to be the best way to achieve this.
