This fixes a regression introduced by
Ia99687815667c3cf5e82cf21d841d3b1008b8fa9
It turns out that [[ -d /usr/lib/grub/*-efi ]] is not a good check,
because [[ doesn't split that and try to glob match ( [ would ). This
has resulted in us triggering this path on ARM64.
This is an x86-64 only check, because on other platforms we either
don't support EFI or are EFI only. Restrict this check to get arm64
working again.

This change removes the uninstall grub2-efi which was required for
prerelease rhel-9 images but now breaks current centos-9-stream
images. A different approach may be required for rhel-9 if the base
image remains different to centos-9-stream (such as populating the
empty /boot/efi partition from the base image)
This change also fixes the detection of whether this is an efi build
to check the block device instead of checking for whether a grub efi
package is installed. This fixes building a centos-9-stream whole-disk
image when package grub2-efi-x64 is installed but a legacy fallback
grub also needs to be installed.

Partial-Bug: #1957789
This reverts I2701260d54cf6bc79f1ac765b512d99d799e8c43,
Idf2a471453c5490d927979fb97aa916418172153 and part of
Iecf7f7e4c992bb23437b6461cdd04cdca96aafa6 which added special flags to
update kernels via grubby.
These changes actually ended up reverting the behaviour on Fedora 35,
which is what led me to investigate what was going on more fully.
All distros still support setting GRUB_DEVICE in /etc/default/grub;
even the BLS based ones (i.e. everything !centos7).
The implementation *is* confusing -- in earlier distros each BLS entry
would refer to the variable $kernelopts; which grub2-mkconfig would
write into /boot/grub2/grubenv. After commit [1] this was reverted,
and the kernel options are directly written into the BLS entry.
But the real problem is this bit from [2]
get_sorted_bls()
{
if ! [ -d "${blsdir}" ] || ! [ -e /etc/machine-id ]; then
return
fi
...
files=($(for bls in ${blsdir}/${machine_id}-*.conf; do
...
}
i.e., to avoid overwriting BLS entries for other OS-boots (?),
grub2-mkconfig will only update those BLS entries that match the
current machine-id.
The problem for DIB is that we are clearing the machine-id early in
finalise.d/01-clear-machine-id, but then running the bootloader update
later in finalise.d/50-bootloader.
The result is that the bootloader entry generated when we installed
the kernel (which guessed at the root= device, etc.) is *not* updated.
Even more annoyingly, the gate doesn't pick this up -- because the
gate tests run on a DIB image that was booted with
"root=LABEL=cloudimg-rootfs" the kernel initially installed with
"install-kernel" (that we never updated) is actually correct. But
this fails when built on a production host.
Thus we don't need any of the explicit grubby updates; these are
reverted here. This moves the machine-id clearing to after the
bootloader setup, which allows grub2-mkconfig to setup the BLS entries
correctly.

As noted inline, the switch to "boot loader spec" grub entries breaks
our setting of the root device. This happened some time ago, and it's

hitting this.

The rhel-8.4 qcow2 base image already has the grub2-efi-x64 package
installed on its single partition which has files installed to
/boot/efi..., however a partitioned image will have an empty /boot/efi
partition when running 50-bootloader. This means dnf will not install
grub2-efi-x64 when requested and /boot/efi will remain empty.
This commit makes the following changes:
- Refactors redhat bootloader pkg-map for the following:
- Make x86_64/amd64, arm64/aarch64 adjancent so they don't diverge
- Map grub-efi to packages installed to /usr
- Map grub-efi-{arch} to packages installed to /boot/efi
- Removes packages grub-efi-{arch} before installing grub-efi and
grub-efi-{arch}

We've noticed that centos8 arm64 images have a root devices of
/dev/mapper/loop7p3 which make sense within a dib image build context
but not at boot time. Dib intends to use labels to set the root device
but when efi is used we end up running grub2-mkconfig against the efi
grub config path before we configure grub to use labels.
Fix this by running grub2-mkconfig after its configuration is set.
This should avoid confusion and complicated paths through the scripts
that configure this for us. We then copy the resulting config to the efi
specific grub.cfg location for platforms that have it.
There is also a small refactoring that is done to try and make the ~3
boot variants more clear:
1) Booting with legacy bios
2) Booting with uefi without a signed shim that directly calls grub
3) Booting with uefi and a signed shim that calls grub
Options 1 and 2 share the /boot/grub*/grub.cfg file. Option 3 needs its
grub.cfg to live alongside distro specific efi target.

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 rhel8.2 .qcow2 images have moved from a single xfs partition into
an EFI style layout with separate /boot/efi partition.
This means the root partition has /boot/grub2/grubenv as a symlink to
../efi/EFI/redhat/grubenv, which is dangling when we are running the
bootloader element as /boot/efi is blank. grub-install tries to call
rename() in the process of re-writing this file, which fails and bails
out dib.
Remove this symlink if it exists

The grub.cfg has two variables [1]
GRUB_CMDLINE_LINUX : used on all boots
GRUB_CMDLINE_LINUX_DEFAULT : additionally used on all "normal" boots
The problem with I2298675dda1f699c572b3423e7274bc8bd7c1c9d is that it
appened the values in DIB_BOOTLOADER_DEFAULT_CMDLINE to both of these,
resulting in duplicated arguments. I don't think we considered that
GRUB_CMDLINE_LINUX_DEFAULT actually already appends to the
GRUB_CMDLINE_LINUX values.
Make DIB_BOOTLOADER_DEFAULT_CMDLINE only append itself to
GRUB_CMDLINE_LINUX_DEFAULT. That seems to line up sensibly with the
name of the variable.
Documentation is enhanced around this, and a releasenote added.

Without this change DIB appends a second command line entry to the GRUB
config. This causes the original command line entry to be ignored
when Linux is booted.
The expected behaviour is that DIB appends to the existing entry as
it does for Ubuntu and SUSE.
Following discussion on the review, this also removes the distro specific
switch statement, as update-grub just calls grub-mkconfig, meaning that
there was nothing distro specific in the first place.

Using the newly exposed variables from the prior change, install the

Change-Id: I0918e8df8797d6dbabf7af618989ab7f79ee9580
Currently we only export "image-block-device" which is the loopback
device (/dev/loopX) for the underlying image. This is the device we
install grub to (from inside the chroot ...)
This is ok for x86, but is insufficient for some platforms like PPC
which have a separate boot partition. They do not want to install to
the loop device, but do things like dd special ELF files into special
boot partitions.
The first problem seems to be that in level1/partitioning.py we have a
whole bunch of different paths that either call partprobe on the loop
device, or kpartx. We have _all_part_devices_exist() that gates the
kpartx for unknown reasons. We have detach_loopback() that does not
seem to remove losetup created devices. I don't think this does
cleanup if it uses kpartx correctly. It is extremley unclear what's
going to be mapped where.
This moves to us *only* using kpartx to map the partitions of the loop
device. We will *not* call partprobe and create the /dev/loopXpN
devices and will only have the devicemapper nodes kpartx creates.
This seems to be best. Cleanup happens inside partitioning.py.
practice. Deeper thinking about this, and more cleanup of the
variables will be welcome.
This adds "image-block-devices" (note the extra "s") which exports all
the block devices with name and path. This is in a string format that
can be eval'd to an array (you can't export arrays).
This is then used in a follow-on
(I0918e8df8797d6dbabf7af618989ab7f79ee9580) to pick the right
partition on PPC.

Currently we have all our elements and library files in a top-level
directory and install them into
<root>/share/diskimage-builder/[elements|lib] (where root is either /
or the root of a virtualenv).
The problem with this is that editable/development installs (pip -e)
do *not* install data_files. Thus we have no canonical location to
look for elements -- leading to the various odd things we do such as a
whole bunch of guessing at the top of disk-image-create and having a
special test-loader in tests/test_elements.py so we can run python
unit tests on those elements that have it.
data_files is really the wrong thing to use for what are essentially
assets of the program. data_files install works well for things like
config-files, init.d files or dropping documentation files.
By moving the elements under the diskimage_builder package, we always
know where they are relative to where we import from. In fact,
pkg_resources has an api for this which we wrap in the new
diskimage_builder/paths.py helper [1].
We use this helper to find the correct path in the couple of places we
need to find the base-elements dir, and for the paths to import the
library shell functions.
Elements such as svc-map and pkg-map include python unit-tests, which
we do not need tests/test_elements.py to special-case load any more.
They just get found automatically by the normal subunit loader.
I have a follow-on change (I69ca3d26fede0506a6353c077c69f735c8d84d28)
to move disk-image-create to a regular python entry-point.
Unfortunately, this has to move to work with setuptools. You'd think
a symlink under diskimage_builder/[elements|lib] would work, but it
doesn't.
[1] this API handles stuff like getting files out of .zip archive
modules, which we don't do. Essentially for us it's returning
__file__.
