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…

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…
