This change replaces the call to grub2-switch-to-blscfg with a file
rename to update it to the actual machine-id.
grub2-switch-to-blscfg has issues in some build environments:
- When the build host is EFI boot, it assumes the image is, and
fails when config file /etc/grub2-efi.cfg is missing
- With recent cento9 images and a fedora build host it fails with:
grub2-probe: error: cannot find a device for / (is /dev mounted?)

Per the bug mentioned upstream, grub2-mkconfig will currently not set
the kernel options for BLS entries prefixed with a machine-id
different to the running system.
This affects the centos element, as the upstream .qcow2 comes with a
pre-existing BLS entry but a blank machine-id. This only affects
9-stream -- prior releases either don't use BLS or have entries
configured to use a common variable from grubenv which is updated
correctly.
We currently can not end-to-end test this in OpenDev because we run
our functional tests on Ubuntu Focal (they use devstack), whose kernel
can not read the XFS format on the 9-stream .qcow2. This expands the
functional tests (that run on Debian Buster, with a later kernel) to
add the vm element, so the bootloader path is exercised (this requires
a block-device too). This at least runs the bootloader install, we
can confirm the kernel options look right from the dumping provided
the logs.

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 python3/python3-pyyaml packages both are never installed and dnf
itself never updated when $DIB_DISTRIBUTION_MIRROR set and used.
This change fix the order of the operations:
1. yum/dnf configure.
2. *.repo patching.
3. yum/dnf update/install execution.

other packages [1].

Also Increase flake8 and pyflakes version in lower-constraints.txt as
this was already broken.

This patch adds support for CentOS 8 Stream [1] to the centos element
(cloud image). Users should set DIB_RELEASE=8-stream.

Other architectures are stored under "altarch" for CentOS 7, update
the match.
Convert the delimiters to "," to avoid a subtle problem with "|" --
POSIX states
Within the BRE and the replacement, the BRE delimiter itself can be
used as a literal character if it is preceded by a backslash.
So "s|\(foo\|bar\)|moo|" doesn't do what you might think; the inner
pipe becomes a literal | and this will *not* match "foo" or "bar".

DIB was retrieving the oldest cloud image file which, presently, means
retrieving CentOS 8.1 instead of CentOS 8.2. Even though DIB runs a
system update and so catches up to latest, this takes bandwidth, time
and final image space (8.1 + system update = 765M qcow2, vs 8.2 + system
update = 518M qcow2).
This patch fixes that by taking the first image name in a descending
order list.

We're ending up with "centoscentos" in the mirror location and the
build fails; strip out the $contentdir from the original too.

* Add "centos" element, a CentOS version-independent element. This is in
line with the same work done for RHEL in Stein cycle.
* Deprecate the centos7 element. CentOS 7 support itself it not
deprecated though. The new "centos" element provides the same support
level as the "centos7" element.
* Add functional testing
The default CentOS version is 8. You can adjust it using the DIB_RELEASE
environment variable.

Several people have popped up in IRC recently with failures in these
elements. Without Python 2.7 available in the image they are
unsupported (OpenStack hasn't supported it for a long time). Remove
these to avoid further confusion.
The centos/centos7 DISTRO split that has happened with centos-minimal
is unfortunate but I don't think it helps to rename centos7/rhel7 ATM.
To summarise; DISTRO=centos7 means image based build,
DISTRO=centos && DIB_RELEASE=7 means the minimal build.
In the future, I think it is important that the minimal builds and
image builds set the same DISTRO. This reflects that "upper" layers
shouldn't care about the exact building of the lower layers. I see
CentOS 8 going one of two ways
1) the changes are so significant, we start separate centos8 /
centos8-minimal elements. They both set DISTRO=centos8 (and
DIB_RELEASE to point-release maybe?). This means we have to update
all "if DISTRO == centos || DISTRO == centos7" branches to also check
for "centos8". Evenually (!) "centos" goes away for versioned DISTRO
only
2) we restore centos element with DISTRO=centos and DIB_RELEASE=8, and
centos-minimal remains the same. This means we have to audit all "if
DISTRO == centos" calls to make sure they're appropriate for version 8
(stick a "&& DIB_RELEASE=7" on them all basically).
I'm not sure we can fully decide until we start to see excatly how the
distro switching/matching bits look, but (2) is consistent with Ubuntu
and probably the preferred solution.
Some "rhel" parts have been cleaned up. More could be done in
rhel-common, but given our lack of coverage of that I'd prefer to
leave it for now.

The dib-run-parts element was copying our internal version of
dib-run-parts into /usr/local/bin to be used running scripts inside
the target chroot. However, it never cleaned up after itself. This
means all images were left with an unmanaged local install of
dib-run-parts.
This copies dib-run-parts into the hooks directory of the chroot and
runs it from there. It is cleaned up automatically on the exit path.
The dib-run-parts element is no longer required and it has been
removed from all dependencies. It is left with a deprecation notice
in the README. For compatability we convert it to simply install
dib-utils.
Codesearch shows no users depending on this unintentional implicit
install. Note os-refresh-config depends on dib-utils and thus will
have an explicitly installed version.

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__.
