The rhel7 element is deprecated and is left only for backward
compatibility.
The rhel element should be used instead. Users should set DIB_RELEASE to
'7' to indicate which release you are using.
The new element is a version-less RHEL element to handle both '7'
and '8' DIB_RELEASE, which aligns with other elements which operate in
the same way such as the Fedora element.

Make a version-less RHEL element to handle both '7' and '8' DIB_RELEASE.
The element usage should align with other elements which operate in the
same way such as the Fedora element.
Additionally, this patch adds support for RHEL8 that operates with
Python 3.
As of now, users of diskimage-builder will still be able to use the
'rhel7' element, or migrate to 'rhel' and specify their respective
DIB_RELEASE value.
* mount the xfs file-system for extraction as read-only. vaguely
based on explaination in [1] and the fact we only read the image
data into a tar, so can ignore this.
XFS (dm-1): Superblock has unknown read-only compatible features (0x4) enabled.
* Use the redhat system python as the dib-python version. dib was
ahead of it's time making an abstracted python interpreter for
system work ;) the system python should work for running the various
dib element scripts.

I want to use the new --image-extra-size flag[1] but my use-case
calls for megabyte granularity of this value. Rather than adding
60% to an 800MB image, maybe I only want to add 100 or 200MB, etc.

Use openSUSE 15.0 as default, which is the latest released stable
openSUSE release. Switch to https for accessing download.o.org
as encrypted transfers should be used by default.
Remove leftovers for definitely unmaintained openSUSE 13.x images
and split into old/new leap style versioning scheme for clarity.

Depending on the version of $DIB_PYTHON_VERSION, we can either use pip /
pip3 to install glean. This is helpful for newer OSes that might not
want to ship python2 (pip).

Currently diskimage-builder supports two ways to specify the image
size. One is defining a fixed image size using DIB_IMAGE_SIZE, the
other one is auto-detection while adding a security margin of 60% as
free space. This means when building larger images (e.g. >100GB) with
unknown size upfront we end up with much wasted space, IO and network
traffic when uploading the images to several cloud providers. This can
be optimized by adding a third way by defining DIB_IMAGE_EXTRA_SIZE to
specify the free space in GB. This makes it possible to easily build
images of varying sizes while still minimizing the overhead by keeping
the free space constant to e.g. 1GB.

In many cases, the statically sized 64MB journal is far below the
e2fstools default calculation[0] which calls for a 64MB journal only
on filesystems smaller than 16GB. On bare metal in particular, the
correct default journal size will often be in the 512MB-1GB range.
Since we cannot know what the target system is, this should be a
tunable parameter that the user can set depending on the intended
image usage.
Add a DIB_JOURNAL_SIZE envvar and --mkfs-journal-size parameter
to the image creation so users can override the default journal
size.

These options have always been a bit of a mess since v2 when we added
all the block-device flexibility. Add some explicit documentation to
try and help explain the relationship between these options and the
block-device config.

Due to the referenced bug, many versions of debootstrap can't bring up
a buster environment. Unfortunately, these include versions we use to
do this on Xenial/Bionic nodes.
Also, there isn't backports or security updates, so elide these for
now.
I did get a working build (I haven't gone so far as a full boot+glean)
with this, at least.

Paritial-Bug: #1822927
Currently, the cleanup script is using the existence of the folder
/sys/fs/selinux to check if SELinux is enabled. This, however, is
misleading in case disk-image-builder is used inside a Docker
container on a selinux-enabled host. In this case, the folder exists
in the container but SELinux is disabled.
This patch addresses the problem by checking, in addition to the
check already in place, the output of the command selinuxenabled.

This is a mechanically generated change to replace openstack.org
git:// URLs with https:// equivalents.
This is in aid of a planned future move of the git hosting
infrastructure to a self-hosted instance of gitea (https://gitea.io),
which does not support the git wire protocol at this stage.
This update should result in no functional change.

This is only one line, but it takes a lot to untangle ... basically
the current "correct" path is:
---
mk_build_dir()
-> sets trap trap_cleanup EXIT
... stuff ..
mount_proc_dev_sys
-> mounts $TMP_MOUNT_PATH/<proc,dev.sysfs>
pre-finalise.d
finalise.d
unmount_image $TMP_BUILD_DIR/mnt # nb == $TMP_MOUNT_PATH
-> unmount_dir()
-> recursive unmount everything inside TMP_MOUNT_PATH
TMP_IMAGE_PATH=$(dib-block-device getval image-path)
export TMP_IMAGE_PATH
dib-block-device umount
dib-block-device cleanup
... actually cleanup directories ...
---
Our current failure exit trap does:
---
dib-block-device umount
unmount_image
...
---
Note this is the *opposite* of what is done in the correct exit path.
In the failure case, if a script fails in the finalise stages it leads
to /proc, /sys, /dev etc. still being mounted inside the image; the
"dib-block-device umount" call doesn't know anything about these
mounts and tries to unmount the parent directory, and we get a hard
failure with a busy mount, and all the mounts are subsequently leaked.
Note that "unmount_dir", which is ultimately called by
"unmount_image", already knows to skip those mounts that
"dib-block-device umount" manages (this is the DIB_MOUNTPOINTS list).
This is further evidence it should be called *before* the
dib-block-device umount.

Add a DIB_APT_MINIMAL_CREATE_INTERFACES boolean to the debootstrap
element which functions identically to
DIB_YUM_MINIMAL_CREATE_INTERFACES in the yum-minimal element.
This can be used to disable the creation of the
/etc/network/interfaces.d/eth[01] dhcp configuration files, which
are not needed on systems where cloud-init or other means are used
to configure networking.
The flag is enabled by default to keep creating the dhcp interface
files, maintaining backwards compatibility.

in same cases it is required to avoid update all existing packages,
doing so can result in release update which is currently not possible
unless you not include "base" element.
"base" element used for most distribution (rhel, debain), and is
necessary for most cloud operations, this patch add
"DIB_AVOID_PACKAGES_UPDATE" parameter to skip updating all packages.
usecases for this patch can be:
* Avoid release update when building old release ex. RHEL7.5.
* build on network-less environment.
usage:
DIB_AVOID_PACKAGES_UPDATE=1
or
DIB_AVOID_PACKAGES_UPDATE=0
