This field indicates that a container was explciitly stopped by
an API call, and did not exit naturally. It's used when
implementing restart policy for containers.

0d2d523390 top: fallback to execing ps(1)
Fallback to executing ps(1) in case we hit an unknown psgo descriptor.
This ensures backwards compatibility with docker-top, which was purely
ps(1) driven.

Also support comma-separated descriptors as input.

0b2c9c2acc Add basic structure of podman init command
As part of this, rework the number of workers used by various
Podman tasks to match original behavior - need an explicit
fallthrough in the switch statement for that block to work as
expected.

Also, trivial change to Podman cleanup to work on initialized
containers - we need to reset to a different state after cleaning
up the OCI runtime.

system: add new subcommand "migrate"
it is useful to migrate existing containers to a new version of
podman.  Currently, it is needed to migrate rootless containers that
were created with podman <= 1.2 to a newer version which requires all
containers to be running in the same user namespace.

Add --read-only-tmpfs options
The --read-only-tmpfs option caused podman to mount tmpfs on /run, /tmp, /var/tmp
if the container is running int read-only mode.

The default is true, so you would need to execute a command like

--read-only --read-only-tmpfs=false to turn off this behaviour.

Internal names do not match external names
We refer to the pause_image and pause_container in the libpod.conf
description, but internally we had infra_image and infra_container.

This means it the user made changes to the conf, it would not effect the
actual tool using libpod.

Fix podman command --change CMD
Currently in Docker if you commit with --change 'CMD a b c'
The command that gets added is

[/bin/sh -c "a b c"]

If you commit --change 'CMD ["a","b","c"]'

You get
[a b c]

This patch set makes podman match this behaviour.

Similar change required for Entrypoint.

f7951c8776 Use GetContainer instead of LookupContainer for full ID
All IDs in libpod are stored as a full container ID. We can get a
container by full ID faster with GetContainer (which directly
retrieves) than LookupContainer (which finds a match, then
retrieves). No reason to use Lookup when we have full IDs present
and available.

The SELinux label for the CRIU dump.log was explicitly set in Podman.
The label for the restore.log, however, not. This just moves the code
to label the log file into a function and calls that functions during
checkpoint and restore.

aef09ce031 Add --include-volumes flag to 'podman commit'
The 'docker commit' will never include a container's volumes when
committing, without an explicit request through '--change'.

Podman, however, defaulted to including user volumes as image
volumes.

and make the default behavior match Docker.

userns: prevent /sys/kernel/* paths in the container
when we run in a user namespace, there are cases where we have not
enough privileges to mount a fresh sysfs on /sys.  To circumvent this
limitation, we rbind /sys from the host.  This carries inside of the
container also some mounts we probably don't want to.  We are also
limited by the kernel to use rbind instead of bind, as allowing a bind
would uncover paths that were not previously visible.

This is a slimmed down version of the intermediate mount namespace
logic we had before, where we only set /sys to slave, so the umounts
done to the storage by the cleanup process are propagated back to the
host.  We also don't setup any new directory, so there is no
additional cleanup to do.
