the podman generate systemd command will generate a systemd unit file
based on the attributes of an existing container and user inputs. the
command outputs the unit file to stdout for the user to copy or

users can set a restart policy as well as define a stop timeout
override for the container.

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.

This ensures that all tmpfs mounts added by the user, even with

Several changes made in the interface of pkg/spec make
interacting with it without a runtime difficult to impossible,
so move the existing limited testing from cmd/podman (which
mostly tested pkg/spec) into pkg/spec itself where we can call

Unify handling for the --volume, --mount, --volumes-from, --tmpfs
and --init flags into a single file and set of functions. This
will greatly improve readability and maintainability.
Further, properly handle superceding and conflicting mounts. Our
current patchwork has serious issues when mounts conflict, or
when a mount from --volumes-from or an image volume should be
overwritten by a user volume or named volume.

Play kube was passing the pod, but CreateConfig was not. Unify it

The goal here is to keep only the configuration directly used to
build the container in CreateConfig, and scrub temporary state
and helpers that we need to generate. We'll keep those internally
in MakeContainerConfig.
Signed-off-by: Matthew Heon <matthew.heon@pm.me>
Right now, there are two major API calls necessary to turn a
filled-in CreateConfig into the options and OCI spec necessary to
make a libpod Container. I'm intending on refactoring both of
these extensively to unify a few things, so make a common
frontend to both that will prevent API changes from leaking out
of the package.

The --read-only-tmpfs option caused podman to mount tmpfs on /run, /tmp, /var/tmp

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

we were previously closing as many FDs as they were open when we first
started Podman in the range (3-MAX-FD). This would cause issues if
there were empty intervals, as these FDs are later on used by the
Golang runtime. Store exactly what FDs were first open in a fd_set,
so that we can close exactly the FDs that were open at startup.

Also, you can now podman-remote run -it. There are some bugs that need
to be ironed out but I would prefer to merge this so we can make both
progress on start and exec as well as the bugs.
* when doing podman-remote run -it foo /bin/bash, you have to press
enter to get the prompt to display. with the localized podman, we had to
teach it connect to the console first and then start the container so we
did not miss anything.
* when executing "exit" in the console, we get a hard lockup likely
because nobody knows what to do.
* custom detach keys are not supported
* podman-remote run -it alpine ls does not currently work. only
dropping to a shell works.

Don't sort OCI hooks using the locale collation order; it does not
make sense for the same system-wide directory to be interpreted differently
depending on the user's LC_COLLATE setting, and the language-specific
collation order can even change over time.
Besides, the current collation order determination code has never worked
with the most common LC_COLLATE values like en_US.UTF-8.
Ideally, we would like to just order based on Unicode code points
to be reliably stable, but the existing implementation is case-insensitive,
so we are forced to rely on the unicode case mapping tables at least.
(This gives up on canonicalization and width-insensitivity, potentially
breaking users who rely on these previously documented properties.)

simplify the rootless implementation to use a single user namespace
for all the running containers.
This makes the rootless implementation behave more like root Podman,
where each container is created in the host environment.
There are multiple advantages to it: 1) much simpler implementation as
there is only one namespace to join. 2) we can join namespaces owned
by different containers. 3) commands like ps won't be limited to what
container they can access as previously we either had access to the
storage from a new namespace or access to /proc when running from the
host. 4) rootless varlink works. 5) there are only two ways to enter
in a namespace, either by creating a new one if no containers are
running or joining the existing one from any container.
Containers created by older Podman versions must be restarted.

Completely remove the WithNetNS() call when we do use an explicit
namespace from a path. We use that call to indicate that a netns
is going to be created - there should not be any question about
whether it actually does.
