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.

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.

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.

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.

avoid the stdout logging, and I wrote it!).
Make it so specifying a --logfile puts dib into quiet mode for stdout.

While trying to get docker image pre-caching to work we couldn't get a
docker daeomon to run within the chrooted environment. However we got
docker running with the help of bwrap outside of the chrooted
environment. The only option so far for this is the block-device.d
phase. But this has the problem that it runs after the image size has
been calculated. This leads to broken builds if the docker images
being pulled are big.
This can be solved by adding a post-root.d phase that runs outside the
chroot but before the image size calculation.

When using the upstream cloud images with the "ubuntu" element, they

In exploring Gentoo caching, it was realised that we have no way to
bind mount the cache into the finalised image for the finalise.d

By adding a pre-finalise.d phase that runs outside the chroot, we can
mount outside things into the hierarchy at $TMP_BUILD_DIR/mnt which
are then seen by the in-chroot finalise.d phase.

Currently there's more-or-less an assumption that a kernel is

doesn't hurt. Move the debootstrap element to the new modprobe

Diskimage-builder fails to build ubuntu-minimal images when run on
a Ubuntu bionic-beaver (18.04) instance.
The user gets "Couldn't create tempfiles for splitting up" when
apt-get update is run in the ubuntu-minimal element root.d.
The issue is that the /tmp inside the chroot is not getting the
proper permissions applied from the base-files package. This is likely
because the pip-cache element has already created the directory before
the base-files package is installed.
This patch changes the order of pip-cache to root.d/11-pip-cache so that
it runs after teh base OS root.d elements run.

The problem with I2298675dda1f699c572b3423e7274bc8bd7c1c9d is that it

A recap -- we run umount phase then cleanup phase.
Currently we register a object to do the final LVM cleanup based on
the parent PV. In light of I697bfbf042816c5ddf170bde9534cc4f0c7279ff,
I believe this should just be done in the cleanup phase. Note there
was probably additional confusion because the partition removal was
done in the cleanup phase until
I7af3c5cf66afd81a481f454b5207af552ad52a32, where is was moved into the
umount phase.
Thus it is moved into the cleanup() function and this should now run,
per the comment, after everything is unmounted in umount phase.
This also exposes that we didn't have the cleanup phase in the unit
tests (because it wasn't doing anything I guess). Add it.

afterwards we try and remove the partitions.

TODO: a test case to ensure the ordering
One call in localloop requires the output of the command, so modify
exec_sudo to buffer up output and return it. This is modelled on the
same thing in package-installs-v2 which seems to work. Rather than
return a subprocess exception, return a dib exception which everything
should have imported anyway.
The overall reason for this is to make our external calls more
consistent for mocking in unit testing.

This element will replace modprobe-blacklist element. It wil
still have the blacklist functionality, but it also adds
the feature of passing a complete file with settings to the
modprobe.d directory. Adding this functionality, that will
allow elements that depends on this module, to just copy the
specified files to the final directory.

As described in blockdevice.py detachment and (most) resources
release must be done in the umount phase of a block device module.
Until now these jobs were done in the lvm cleanup() phase - which
is too late - especially when using nested LVMs.
This patch moves the functionality of the cleanup() phase to the
umount() phase for the lvm module.
It includes a test case that fails without applying the provided
source code changes.

Our sgdisk calls are putting extra double-quotes around the names of
partitions. This confuses sfdisk, which confuses growpart, which
confuses growroot ... and you don't get your partition grown for EFI
boot.
Ensure we just bunch arguments into the list directly (for Popen)
rather than string split and have to worry about quoting. Add a check
for this to our GPT unit test, extending it to include a space in the
name of the root partition.

The existing directories are needed for stage building (a part of the
Gentoo build process). Normally these directories are empty, but there
are times where overrides need to be defined. This commit handles
existing overrides for keywords. For historical reasons the overrides
were able to be put in different files and directories, this
centralizes them.
This also updates the version of openssl/cryptography that works with
or without bindist.

This patch adds an element that handles the configuration for
creating a disk capable of being a remote root filesystem through
iSCSI on CentOS images.
Tested on Fujitsu Server and boot with BIOS and UEFI mode successfully.
- Tested Boot-From-Volume + EFI for centos7 with following elements:
"centos7 vm devuser cloud-init-datasources dhcp-all-interfaces
iscsi-boot dracut-regenerate block-device-efi"

According to http://bit.ly/2HA4oDO and
the official Ubuntu manual
http://manpages.ubuntu.com/manpages/xenial/man5/interfaces.5.html
source-dir support has been removed from Ubuntu >= 16.04/Xenial
Once an image is generated and booted, moving the dhcp interface(s)
declaration(s) from /etc/network/interfaces into specific subentries
of /etc/network/interfaces.d and calling 'service networking restart'
just make your instance unreachable and all interfaces are left
unconfigured.
This patchset fixes this issue
