This started a long way from here, when I noticed that "top" on centos
9-stream images wasn't working because ncurses-base wasn't installed.
This led me to the extant install of bash/glibc/ncurses-libs from
Iecf7f7e4c992bb23437b6461cdd04cdca96aafa6. However it didn't really
explain why these are brought in here.
Reading further it became clearer that over the years of distribution
additions, Fedora updates, etc. this has grown into a bit of a mess.
Refactor the release package installs into a more logical flow,
pulling out checks/comments for Fedora's of ancient history, etc.
Remove the 9-stream package installs; this isn't the place for them,
and the should be brought in by the base packages.
Ultimately, this is intendend to a be a no-op refactor.

The recent git ownership-checking changes (see related bug for full
details) mean we can not run git in non-owned directories.
We have a couple of cases here where we have done a "pushd" to work in
the REPO_DEST context; this is the destination directory that is
inside the chroot so needs to be operated on as "root" (via sudo
calls). This certainly makes sense -- but given the new way of things
it can hide what context each call is working in, which is now very
important. Previously this worked because you could read it; now it's
doing the UID check too, calls in here without sudo now fail.
Remvoe the pushd's and make every call that works in REPO_DEST
explicit with -C, and add sudo calls around it.

The bootloader element installs the grub bootloader for whole-disk
images, but it also correctly sets values in /etc/default/grub and BLS
entries.
This value setting is useful even if the bootloader isn't installed.
For example, the overcloud-full partition image benefits from a
correct /etc/default/grub and BLS entries which ironic-python-agent
will use when it installs grub on the disk during baremetal deploy.
This change moves the actual grub install to the end of the script,
and if there is no $DIB_BLOCK_DEVICE set then install is skipped.
This allows overcloud-full to use the bootloader element instead of
the grub2 element, so the correct grub defaults are set on centos9,
including the correct root device on centos9.

This change is proposed again, avoiding lsblk features missing from

RHEL-9 base images are whole-disk images with the /boot/efi partition
correctly set up for EFI Secure Boot. This doesn't work with
extract-image because it only mounts the root partition, leaving
/boot/efi empty even though grub2-efi & shim packages are "installed".
This change mounts discovered partitions to mnt/boot, mnt/boot/efi so
all content can be extracted from the image.
Partition detection is done by reading block device attributes and
matching on Boot Loader Specification[1] UIDs or labels as observed in
supported base images.

Similar to the CentOS-9-Stream fix [1] this change renames the default
BLS entry to match the current machine-id so that grub2-mkconfig calls
will refresh the kernel options.
However there is an additional issue with the rhel-9 base image. It is
unique in having a dedicated boot partition, so the path to the kernel
and initramfs don't include /boot. This results in an unbootable image
when /boot is a directory of the root partition.
These paths do not get corrected by calling grub2-mkconfig, so this
change performs a sed on the paths to fix them for a root partition
/boot.

The check removed here came in with
I4481b43e4a8fe4144be9c7eb9d9c618bbb2df21e a long time ago. At that
time we were not building EFI images, and were building i386 images;
both of which are now untrue.
We can simplify this now by merging it into the gpt/mbr path. If we
are in there we know that we should set --target=i386-pc for BIOS
boot. For sanity check that we are x86 in this path -- PPC is handled
separately (although it's probably bit-rotted) and ARM64 is EFI.

For centos stream, the $releasever is just the major version. Several

NetworkManager is quite capable to do automatic
interface configuration. NetworkManager will by default
try to auto-configure any interface with no configuration.
It will use DHCP for IPv4 and Router Advertisements to
decide how to initialize IPv6.
It will most likely do it just as good, or better than the
dhcp-all-interfaces.sh script.
Since dhcp-all-interfaces clean out all ifcfg files in
60-remove-cloud-image-interfaces it means NetworkManager will
by default attempt auto configuration for all interfaces.
This change add's and environment variable:
DIB_DHCP_NETWORK_MANAGER_AUTO (default: false)
When DIB_DHCP_NETWORK_MANAGER_AUTO is set to `true` only the
NetworkManager config will be written. The dhcp-all-interfaces
service will not be installed. Hence dhcp-all-interfaces will
not write any config files, allowing NetworkManager to just do

because grub2 cannot find the neccecary files when

this package. Since it is now there, the Centos 9 specific
block is no longer needed.

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.

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.

A recent(-ish) change in git [1] has exposed a bug in caching that
appears in one very specific circumstance -- updating the
openstack/openstack super-repo [2].
This repo gets a submodule update every time something is pushed. By
using "--git-dir" while the cwd is one-level above the actual repo we
are confusing [1] which is not finding the submodule directories
correctly and giving us an error:
Could not access submodule 'foo'
for every submodule that has updated between now and the last time we
updated the cache. [3]
The git manual does warn about this
If you just want to run git as if it was started in <path> then use
git -C <path>.
Indeed, that is what we want to do in this path. Modify the calls to
use -C.

again.

A good example of such a package upstream is rdo-release[1] which
includes multiple repo files, the repo keys, and a root certificate.
This makes these repos impractical to install via DIB_YUM_REPO_CONF.
Downstream, repo packages like this a frequently used to bootstrap
development builds of RHEL with development repos.

Fedora 30 and RHEL-8.2 onwards support the Bootloader Spec and use grubby
to manage kernel menu entries and kernel arguments.

This change detects if this is a BLS enabled environment, and uses
grubby to set kernel arguments on all kernel entries if it is.

If the grubenv is regenerated, its changes won't be available to UEFI
boot systems unless the changed grubenv is copied to the EFI
directory.
This change copies the grubenv to the EFI directory when the grub.cfg
is copied.

Debian stable security repos is now stable-security, as well as other
versions.
Move the Debian bullseye job from experimental to non-voting check.

The latest Debian bullseye release doesn't provide yum any more, only
DNF. This breaks the minimal builds that are using on-host yum tools
to start the chroot. Probe for yumdownloader, and if it's not there,
use DNF.
Note this requires "dnf download" which may not be packaged. See
I21cfbd3935e48be4b92591ea36c7eed301230753 for a sample work-around
that installs this plugin in the nodepool-builder container.

Add openeuler-minimal element and add CI functional tests for both
x86_64 and arm64.
OpenEuler is an open source community driven YUM/DNF distro like
Fedora. It references Fedora and CentOS a lot for the rpm packages
building. So somewhat it can be treated as a redhat family distro
and reuse the YUM/DNF related elements to help build openEuler images.
For more info about openEuler, see: https://openeuler.org/en

This change permits the yum-minimal element to be used in downstream
custom distributions, which may have additional packages containing repo
config or GPG keys needed.
This could also be utilized at a later time to move the
distribution-specific logic in this method to each distribution element
separately.
