  script_tag(name:"insight", value:"This update for conmon, fuse-overlayfs, libcontainers-common, podman fixes the following issues:

podman was updated to v2.0.6 (bsc#1175821)

install missing systemd units for the new Rest API (bsc#1175957) and a
 few man-pages that where missing before

Drop varlink API related bits (in favor of the new API)

fix install location for zsh completions

 * Fixed a bug where running systemd in a container on a cgroups v1 system
 would fail.
 * Fixed a bug where /etc/passwd could be re-created every time a
 container is restarted if the container's /etc/passwd did not contain
 an entry for the user the container was started as.
 * Fixed a bug where containers without an /etc/passwd file specifying a
 non-root user would not start.
 * Fixed a bug where the --remote flag would sometimes not make remote
 connections and would instead attempt to run Podman locally.

Update to v2.0.6:

Features

 - Rootless Podman will now add an entry to /etc/passwd for the user who
 ran Podman if run with --userns=keep-id.
 - The podman system connection command has been reworked to support
 multiple connections, and re-enabled for use!
 - Podman now has a new global flag, --connection, to specify a
 connection to a remote Podman API instance.

Changes

 - Podman's automatic systemd integration (activated by the
 --systemd=true flag, set by default) will now activate for containers
 using /usr/local/sbin/init as their command, instead of just
 /usr/sbin/init and /sbin/init (and any path ending in systemd).
 - Seccomp profiles specified by the --security-opt seccomp=... flag to
 podman create and podman run will now be honored even if the container
 was created using --privileged.

Bugfixes

 - Fixed a bug where the podman play kube would not honor the hostIP
 field for port forwarding (#5964).
 - Fixed a bug where the podman generate systemd command would panic on
 an invalid restart policy being specified (#7271).
 - Fixed a bug where the podman images command could take a very long
 time (several minutes) to complete when a large number of images were
 present.
 - Fixed a bug where the podman logs command with the --tail flag would
 not work properly when a large amount of output would be printed
 ((#7230)[[link moved to references]]).
 - Fixed a bug where the podman exec command with remote Podman would not
 return a non-zero exit code when the exec session failed to start
 (e.g. invoking a non-existent command) (#6893).
 - Fixed a bug where the podman load command with remote Podman would did
 not honor user-specified tags (#7124).
 - Fixed a bug where the podman system service command, when run as a
 non-root user by Systemd, did not properly handle the Podman pause
 process and would not restart properly as a result (#7180).
 - Fixed a bug where the --publish flag to podman create, podman run, and
 podman pod create did not properly handle a host IP of 0.0.0.0
