"This is a version update for podman to version 1.4.4 (bsc#1143386).

Additional changes by SUSE on top :

  - Remove fuse-overlayfs because it's (currently) an
    unsatisfied dependency on SLE (bsc#1143386)

  - Update libpod.conf to use correct infra_command

  - Update libpod.conf to use better versioned pause
    container

  - Update libpod.conf to use official kubic pause container

  - Update libpod.conf to match latest features set:
    detach_keys, lock_type, runtime_supports_json

  - Add podman-remote varlink client

Version update podman to v1.4.4 :

  - Features

  - Podman now has greatly improved support for containers
    using multiple OCI runtimes. Containers now remember if
    they were created with a different runtime using
    --runtime and will always use that runtime

  - The cached and delegated options for volume mounts are
    now allowed for Docker compatability (#3340)

  - The podman diff command now supports the --latest flag

  - Bugfixes

  - Fixed a bug where rootless Podman would attempt to use
    the entire root configuration if no rootless
    configuration was present for the user, breaking
    rootless Podman for new installations

  - Fixed a bug where rootless Podman's pause process would
    block SIGTERM, preventing graceful system shutdown and
    hanging until the system's init send SIGKILL

  - Fixed a bug where running Podman as root with sudo -E
    would not work after running rootless Podman at least
    once

  - Fixed a bug where options for tmpfs volumes added with
    the --tmpfs flag were being ignored

  - Fixed a bug where images with no layers could not
    properly be displayed and removed by Podman

  - Fixed a bug where locks were not properly freed on
    failure to create a container or pod

  - Fixed a bug where podman cp on a single file would
    create a directory at the target and place the file in
    it (#3384)

  - Fixed a bug where podman inspect --format '((.Mounts))'
    would print a hexadecimal address instead of a
    container's mounts

  - Fixed a bug where rootless Podman would not add an entry
    to container's /etc/hosts files for their own hostname
    (#3405)

  - Fixed a bug where podman ps --sync would segfault
    (#3411)

  - Fixed a bug where podman generate kube would produce an
    invalid ports configuration (#3408)

  - Misc

  - Updated containers/storage to v1.12.13

  - Podman now performs much better on systems with heavy
    I/O load

  - The --cgroup-manager flag to podman now shows the
    correct default setting in help if the default was
    overridden by libpod.conf

  - For backwards compatability, setting
    --log-driver=json-file in podman run is now supported as
    an alias for --log-driver=k8s-file. This is considered
    deprecated, and json-file will be moved to a new
    implementation in the future
    ([#3363](https://github.com/containers/libpo\
    d/issues/3363))

  - Podman's default libpod.conf file now allows the crun
    OCI runtime to be used if it is installed

Update podman to v1.4.2 :

  - Fixed a bug where Podman could not run containers using
    an older version of Systemd as init

  - Updated vendored Buildah to v1.9.0 to resolve a critical
    bug with Dockerfile RUN instructions

  - The error message for running podman kill on containers
    that are not running has been improved

  - Podman remote client can now log to a file if syslog is
    not available

  - The podman exec command now sets its error code
    differently based on whether the container does not
    exist, and the command in the container does not exist

  - The podman inspect command on containers now outputs
    Mounts JSON that matches that of docker inspect, only
    including user-specified volumes and differentiating
    bind mounts and named volumes

  - The podman inspect command now reports the path to a
    container's OCI spec with the OCIConfigPath key (only
    included when the container is initialized or running)

  - The podman run --mount command now supports the
    bind-nonrecursive option for bind mounts

  - Fixed a bug where podman play kube would fail to create
    containers due to an unspecified log driver

  - Fixed a bug where Podman would fail to build with musl
    libc

  - Fixed a bug where rootless Podman using slirp4netns
    networking in an environment with no nameservers on the
    host other than localhost would result in nonfunctional
    networking

  - Fixed a bug where podman import would not properly set
    environment variables, discarding their values and
    retaining only keys

  - Fixed a bug where Podman would fail to run when built
    with Apparmor support but run on systems without the
    Apparmor kernel module loaded

  - Remote Podman will now default the username it uses to
    log in to remote systems to the username of the current
    user

    support it, allowing for better error reporting

    with a go library for importing values

    used to migrate containers between Podman installations
    on different systems.

  - The podman cp now supports pause flag.

  - The remote client now supports a configuration file for
    pre-configuring connections to remote Podman
    installations

  - CVE-2019-10152: Fixed an iproper dereference of symlinks
    of the the podman cp command which introduced in version
    1.1.0 (bsc#1136974).

  - Fixed a bug where podman commit could improperly set
    environment variables that contained = characters

  - Fixed a bug where rootless podman would sometimes fail
    to start containers with forwarded ports

    when printing the command being executed

  - Fixed a bug where filtering images by label did not work

  - Fixed a bug where specifying a bing mount or tmpfs mount
    over an image volume would cause a container to be
    unable to start

    containers with named volumes

    libraries with numerous bugfixes

    cp

    Podman's configuration files
    (/etc/containers/libpod.conf and
    /usr/share/containers/libpod.conf) if not overridden in
    the rootless configuration

  - Added fuse-overlayfs dependency to support overlay based
    rootless image manipulations

  - The podman cp command can now read input redirected to
    STDIN, and output to STDOUT instead of a file, using -
    instead of an argument.

  - The podman remote client now displays version
    information from both the client and server in podman
    version

  - The podman unshare command has been added, allowing easy
    entry into the user namespace set up by rootless Podman
