Implement a policy for selecting a seccomp profile. In addition to the
default behaviour (default profile unless --security-opt seccomp is set)
add a second policy doing a lookup in the image annotation.
If the image has the "io.containers.seccomp.profile" set its value will be
interpreted as a seccomp profile. The policy can be selected via the
new --seccomp-policy CLI flag.
Once the containers.conf support is merged into libpod, we can add an
option there as well.
Note that this feature is marked as experimental and may change in the
future.

Add a --new flag to podman-generate-systemd to create a new container
via podman-run instead of starting an existing container.
Creating a new container presents the challenge to find a reverse
mapping from a container to the CLI flags it can be created with. We
are doing this via `(Container).Config.CreateCommand` field, which
includes a copy of the process' command from procFS at creating time.
This field may not be useful when the container was not created via the
Podman CLI (e.g., via a Python script). Hence, we do not guarantee the
correctness of the generated files.

Add an --ignore flag to podman rm and stop. When specified, Podman will
ignore "no such {container,pod}" errors that occur when a specified
container/pod is not present in the store (anymore). The motivation
behind adding this flag is to write more robust systemd services using
Podman. A user might have manually decided to remove a container/pod
which would lead to a failure during the `ExecStop` directive of a
systemd service referencing that container/pod.

Add a --cidfile flag to podman rm/stop to pass a container ID via a

for a better life-cycle management in systemd services. Note that
--cdifile can be specified multiple times to rm/stop.

When a cgroup namespace is used, processes inside the namespace are

Signed-off-by: Matthew Heon <matthew.heon@pm.me>
Previously, when `podman run` encountered a volume mount without
separate source and destination (e.g. `-v /run`) we would assume
that both were the same - a bind mount of `/run` on the host to
`/run` in the container. However, this does not match Docker's
behavior - in Docker, this makes an anonymous named volume that
will be mounted at `/run`.
We already have (more limited) support for these anonymous
volumes in the form of image volumes. Extend this support to
allow it to be used with user-created volumes coming in from the
`-v` flag.
This change also affects how named volumes created by the
container but given names are treated by `podman run --rm` and
`podman rm -v`. Previously, they would be removed with the
container in these cases, but this did not match Docker's
behaviour. Docker only removed anonymous volumes. With this patch
we move to that model as well; `podman run -v testvol:/test` will
not have `testvol` survive the container being removed by `podman
rm -v`.
The sum total of these changes let us turn on volume removal in
`--rm` by default.

"init" is a quite common name for the command executed in a container

"/usr/sbin/init".

CRI-O defaults to 1024 for the maximum pids in a container. Podman
should have a similar limit. Once we have a containers.conf, we can
set the limit in this file, and have it easily customizable.
Currently the documentation says that -1 sets pids-limit=max, but -1 fails.
This patch allows -1, but also indicates that 0 also sets the max pids limit.
