   An update that has 8 recommended fixes can now be installed.


   This update for python-kiwi provides the following fixes:
   - Fix some code issues reported by new flake8 version.

   - Change the default value for bundler compression. If no compression is
     configured in the kiwi config file, the default was set to False.
     However this led to problems on the OBS side for images which have fixed
     storage disk sizes configured (for example Azure images which request
     30G disk size per instance). Thus the default changed to True.

   - Fix grub theme lookup. If the theme was not found at the expected place
     an exception was thrown. However the alternative lookup code in /boot
     was not reached with that exception.

   - Add a runtime check for preferences metadata, specifically verifying
     that there is a packagemanager defined and an image version defined.

   - Support alternative EFI and grub modules paths. In SUSE products EFI
     binaries are historically located in /usr/lib*/efi. In a recent move to
     package grub2 as noarch, a collision between x86_64 and aarch64 has been
     identified, as both place platform-specific files to the same location.
     To fix this, a new location was devised: /usr/share/efi/$(uname -m). At
     the same time /usr/lib/grub2 will move to /usr/share/grub2. (fate#326960)

   - Fix Xen guest detection. Xen setup (e.g in the Amazon Cloud) is only
     supported for the x86_64 architecture. (bsc#1123186, bsc#1123185)

   - Fix the location of grub unicode font file. grub2 is expecting the
     unicode font under the fonts directory in the /boot/grub*/ depending on
     how the distribution installs grub2. (bsc#1119416)

   - Add container history metadata on umoci repack call. This change makes
     sure that `umoci repack` call includes history metadata and skips that
     in `umoci config` call.

   - Do not assume package manager is always there. This change modifies the
     behavior for zypper to not assume rpm binary is always part of the
     image. An image could be bootstrapped only without zypper or rpm, in
     that case it does not make sense and it is not possible to dump and
     reload the rpmdb.

   - Allow to switch off install image boot timeout. This commit adds a new
     attribute called: <type ... install_continue_on_timeout="true|false"/>
     It allows to setup the boot timeout for install images build with KIWI.
     If not set or set to 'true', the configured boottimeout or its default
     applies to the install image as it was before. If set to 'false' there
     will be no timeout in the install image bootloader setup and the boot
     only continues on manual intervention.

   - Make result compression in the bundler optional. Calling kiwi result
     bundle will take the image build results and bundle the relevant image
     files according to their image type. Depending on the result
     configuration this could instruct the bundler to compress
     one or more files from the result. If compression is activated the
      result image has to be uncompressed before it can be used.

   - Fix using SysConfig objects. Objects of that class do not provide a get
     method but
     overload the bracket [] operator. Using the get() method would fail.

   - Use chkstat to verify and fix file permissions. Call chkstat in system
     mode which reads /etc/sysconfig/security to determine the configured
     security level and applies the appropriate permission definitions from
     the /etc/permissions* files. It is possible to provide those files as
     overlay files in the image description to apply a certain permission
     setup when needed. Otherwise the default setup as provided on the
     package level applies. It is required that the image root system has
     chkstat installed. If not present KIWI will skip this step and continue
     with a warning.

   - Allow setting the protocol to tcp or upd (e.g. "80/tcp") for exposed
     container ports. If no protocol is provided, OCI defaults are applied.

   - Fix disk size calculation for VMX. Disk size calculation must take into
     account the empty volumes that are to be mounted in a directory that
     does not exist in the root tree,
     otherwise there is KeyError. The result of
      storate/setup._calculate_volume_mbytes must be a dict including all
      defined volumes.

   - More clarity on kernel version lookup. Lookup of the kernel version is
     done by directly reading the kernel image via a small tool named
     kversion. The scope of the tool is limited and does not work for e.g
     kernel images which contain their own decompressor code. For the special
     cases exceptions were defined, one was zImage. The recently added
     exception for vmlinuz seemed too intrusive and was also not well
     documented. This change tries to clarify and get back to explicit and
     easy to read coding.

   - Refactor kernel version lookup. Check the presence of the gzip
     compressed kernel binary and use it. If not present use the arbitrary
     kernel image format with the known limitations.

   - Refactor OCI tools. In order to provide buildah support some of the
     logic about temporary directories for OCI images creation needed to be
     moved to the dedicated OCI tool class. While umoci can operate in any
     directory and this is passed as an argument, this is not the case for
     buildah. In buildah workflow the storage path of work-in-progress images
     and containers and the mountpoint of the container rootfs are not

   - Use cow file on persistent grub live loop boot. When using tools like
     live-grub-stick, the live iso as generated by kiwi will be copied as
     file on the target device and a grub loopback setup is created there to
     boot the live system from file. In such a case the persistent write
     setup which tries to create an extra write partition on the target fails
     in almost all cases because the target has no free and unpartitioned
     space available. Therefore in case of such a loopback mounted system we
     create a cow file (live_system.cow) instead of a partition to setup
     persistent writing. The cow file will be created in the same directory
     the live iso image file was read from grub.

   - Better exception handling in OEM installer. If an error condition
     applies in the kiwi dump dracut code, the reaction was to stop the
     process with a dracut die() call. If the
     option 'rd.debug' was set on boot, this lead to a debugging shell which
      is good, but in a standard process this lead to a lock of the machine
      which is an unfortunate situation. This fix changes the behavior to
      always print the error message as a dialog message box
     on the primary console and reboot the system after keypress or timeout.
      In case of the debug switch configured the system die()'s as before.

   - Add parted dependency for dracut-kiwi-live package. dracut-kiwi-live
     requires the `partprobe` tool and this is provided by parted package.
     Persistent overlay setup fails if parted is not installed in the image.

   - Add support for --no-history umoci's flag. By using this flag kiwi
     appends only a single history entry for OCI containers.

   - Improve dialog usage in kiwi-dump-image. Dialog's "--radiolist" feature
     requires to navigate to the item, press "space" to select the item and
     then "enter" to execute. With "--menu", it is enough to just navigate to
     the item and press "enter" to execute, which is much more intuitive for
     most users.

   - Fixed OEM installer. In the implementation of the ramdisk installer, an
     error for the standard case was introduced such that the lsblk call was
     invalid. This led to no devices being present for the installation.

   - Fix rsync call for filesystem images. For filesystem images the rsync
     call was missing a trail slash for the source path causing the sync to
     include also the containing directory. With this change the filesystem
     image does not include the rootfs in any subdirectory.

   - Add history metadata for container builds. This change adds the history
     section in containerconfig. With that, 'author', 'created_by' and
     'comment' can be customized. In addition, 'created' is always included
     with the image creation date time. 'created_by' entry is set to 'KIWI
     __version__' by default if nothing is provided.

   - Change bundling of image formats. By default none of the image formats
     were stored as compressed files. The reason behind this was the
     assumption that some formats automatically make use of compression,
     which is true but only in their processing and not in their data blocks
     at creation time. Storage and handling of the image file itself becomes
     cumbersome and therefore the default bundle setup for image formats was
     changed to be compressed. This means the image, as it gets packed by
     KIWI, needs to be uncompressed before use. The following image formats
     are affected by the change in a call of the result bundler:
     * qcow2 (.qcow2.xz)
     * vdi   (.vdi.xz)
     * vhd   (.vhd.xz)
     * vhdx  (.vhdx.xz)
     * vmdk  (.vmdk.xz)

   - Fixed firmware strip and lookup for kiwi initrd. In a kiwi initrd the
     function baseStripFirmware can be used to strip down the firmware to the
     actually used kernel drivers in that initrd. The code to do this was
     broken due to some other changes. This change fixes the method to work
     correctly again.

   - kiwi-partitions-lib: Wait for udev before lsblk. An LVM-enabled OEM
     image spuriously did not resize its PV / LVs due to lsblk sometimes
     racing with udev and the disk was just not available during
     get_partition_node_name(). Call udev_pending() before all lsblk calls to
     avoid that. (the lsblk man page also advocates this to synchronize with

   - Refactor containerconfig xml evaluation. This change refactors the
     extracted data from containerconfig section to be tool agnostic.

   - Support ramdisk deployment in OEM images. Using the boot
     option enables the deployment into a ramdisk. If this option is enabled,
     only ramdisk devices as provided by the brd kernel driver will be
     available for deployment.

   - Distinguish install and image dracut config. This fix distinguishes the
     files that should be installed inside the image dracut only than the
     ones installed in both, in install initrd and image initrd.

   - Apply OCI interface for container and root_import. Instead of directly
     calling the container archiving tool, in this case umoci, the code has
     been changed to use the new OCI interface class.

   - Added OCI tooling interface class. An initiative to formulate industry
     standards around container formats and runtime is available at Different tools to implement the
     specifications had been created. The purpose of this class and its
     sub-classes is to provide a common interface in kiwi to allow using all
     tools such that the container support in kiwi covers every linux
     distribution no matter what tooling was preferred.

   - Warn on modifications to intermediate configuration files. Some files
     are taken from the host and managed as intermediate config files during
     the build of the image. Changes to those files during the build run by
     e.g a script will not become effective because the file gets restored.
     With this fix the modification condition is detected and a warning
     message is displayed so that the author of the image can adapt the
     description as suggested in the message.

   - Move the default rpm database path into Defaults class.

   - Add a hardcoded rpm database path to import trusted keys so that they
     are in the expected location for zypper.

   - Allow simple path source in Uri class. This patch is needed as follow up
     fix for the setup of the package cache in local repositories. The
     is_remote method from the Uri class is used to identify if a repository
     source is remote or local. At that point the initial repository source
     was already translated into its components. In case of a local
     repository the Uri instance now receives a simple path and the is_remote
     method raised with a style error.  This patch allows the Uri class to be
     more friendly and initializes a local path as file:/ typed source.

   - Do not cache packages from local repos for zypper. Access to packages
     from local repositories is as fast as reading them from a cache
     location. The additional package copy and cache update is superfluous
     and should be avoided.

   - Update /etc/machine-id management docs. Update the information about how
     /etc/machine-id is treated in KIWI and provide some hints for old
     systems where /var/lib/dbus/machine-id is not a symlink to

   - Added machine id setup in dracut preparation. In case of a dracut booted
     image we empty
     out the systemd machine-id configuration file to trigger the rebuild of
      that information by the dracut boot code at boot time. This allows for
      unique systemd identifiers if the same image gets deployed on different
      machines. This also obsoletes the scripts people put in in or to solve this problem  obsolete.

   - Add Codec utils for bytes literals decoding. In case of a literal
     decoding failure it tries to decode the result in utf-8. This is handy
     in python2 environments where python and the host might be using
     different charset configurations. In python3 this issue seems to be
     solved. (bsc#1110871)

   - Include livenet module with dmsquash-live support. The upstream dracut
     dmsquash-live module supports network mode with the livenet module. But
     that module must be explicitly included and is not fetched automatically.

   - Fixed URI handling with token query option. So far only the query format
     "?credentials=" was supported. In case of "?random_token_data" the
     returned uri was truncated and also the format check on the query caused
     a python trace. (bsc#1110869, bsc#1108508)

   - Make use of the quiet flag of mountpoint command. This sets the use of
     -q flag of mountpoint. Kiwi only checks the return code, thus any stdout
     is useless in this case.

   - Fixes LVM based image creation in OBS. Attempting to create LVM based
     images under the Open Build Service would run into some issues related
     to the fact that there is no udev running in the chroot environment used
     to build kiwi based images. Two workarounds have been implemented in
     this patch: 1. When calling lvcreate, include the `-Zn` option to
     disable the automatic zeroing of the header of the newly created LV
     device. Doing so requires that the LV device's /dev entry exists
     immediately after it has been created, but in a chroot environment udev
     is not going to be running to automatically populate
        or /dev/mapper/<vg_name>-<lv_name>. This should be safe to do since
         the LV is being created within a loopback device based partition,
         which is backed by a zero filled file, created by qemu-img. 2. After
         creating an LV we need to run `vgscan --mknodes` to create the
         required device nodes under /dev, which won't be automatically
         created since udev is not running in the chroot environment.

   - Fix disk size calculation for VMX. Disk size calculation must take into
     account the empty volumes that are to be mounted in a directory that
     does not exist in the root tree
     otherwise there is KeyError. The result of
      storate/setup._calculate_volume_mbytes must be a dictionary including
      all defined volumes.

   - Fixed disk detection from root device. The method
     lookup_disk_device_from_root assigns the disk device matching the root
     device uuid. However in a multipath environment multiple disk devices
     matches the same root device. The code to assign the multipath map in
     this case was missing in the dracut code base. (bsc#1126283, bsc#1126318)
