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.

Related to I041a141366099093805e6052b1bbf64efd277e1e, we also need to
remove this on opensuse. The files for gate testing are added, but
the test is not added to any jobs at this point in the interests of
gate time.

This fixes a regression in I041a141366099093805e6052b1bbf64efd277e1e
where we starting skipping the removal of old files for image-based
builds (confusingly named centos7 rather than centos for historical
reasons). Fix the check

As described inline, we only want to remove the system package files
on centos; it causes problems on Fedora where some system tools expect
these to be there.
But there is an additional bug -- pip actually removes the system
package files anyway. To work around this, reinstall the system
package.

As described in the comments, it seems the transition between
dbus-daemon -> dbus-broker in Fedora 29 has made it so the packages
can get into a state where neither service is enabled.
Explicitly install and enable dbus-broker for F29

The path $TMP_BUILD_DIR/mnt becomes the / inside the chroot during
the chroot phases of diskimage-builder. Previously this path was being
created using the account running diskimage-builder. This account may
not be valid inside the chroot. This causes path validation, when running
on a Ubuntu bionic host, to fail.
This patch chown's the $TMP_BUILD_DIR/mnt to root.root to make sure
that / is owned by a valid account inside the chroot.

There is an use of get_image_element_array on the environment.d
phase, for the iscsi-boot element.
This function is not available on that step. So moving the check
at next step, extra-data-d, where it is available.

This plumbs through an "--use-nm" flag to glean which instructs it to
setup interface bringup with NetworkManager rather than legacy network
enablement scripts.
In this case, install the NetworkManager package. In the non-nm case,
also install the network-scripts for Fedora 29 -- this has stopped
being installed by default (it's been deprecated since forever).
As noted in the docs, this is currently really only relevant on the
supported rpm distros which are using the ifcfg-rh NetworkManager
plugin to effectively re-use old config files. However,
NetworkManager has similar plugins for other platforms, so support can
be expanded if changes are proposed.

Provide a "when" option that provides for not installing packages
based on a = or != match on an environment variable.
Unit tests are added.

It looks like we dropped running these probably when we moved the
elements around. For testtools to find the test scripts we need to
add the __init__.py files to make the directories look like modules.
Also prevent copying any .pyc or cache files in as hooks.
