From a security point of view, it would be nice to be able to map a
rootless usernamespace that does not use your own UID within the
container.
This would add protection against a hostile process escapping the
container and reading content in your homedir.

This is an enhancement proposal for the checkpoint / restore feature of
Podman that enables container migration across multiple systems with
standard image distribution infrastructure.
A new option `--create-image <image>` has been added to the
`podman container checkpoint` command. This option tells Podman to
create a container image. This is a standard image with a single layer,
tar archive, that that contains all checkpoint files. This is similar to
the current approach with checkpoint `--export`/`--import`.
This image can be pushed to a container registry and pulled on a
different system. It can also be exported locally with `podman image
save` and inspected with `podman inspect`. Inspecting the image would
display additional information about the host and the versions of
Podman, criu, crun/runc, kernel, etc.
`podman container restore` has also been extended to support image
name or ID as input.

We already have ipv6 enabled as default via the containers.conf setting.
However the documentation did not reflect this. Also if no options were
set in contianers.conf it would have ipv6 disabled.
We can now remove the extra option from containers.conf.
Also fix another outdated option description for host.containers.internal
and add that the options can also be set in contianers.conf.

The podman machine ls command would benefit from a --quiet flag which
would only print the machine names without the extra information. It
also implies --noheader as well. This can be helpful for scripting with
the podman cli.

This reverts commit e133a06d2f4a3e94bfbd60b647046f2f515c9c24.
@nalind found a proper fix in c/storage [1] to address the performance
issue. So we really don't need the flag anymore. Note the flag has
never made it into any release.

affect the socket forwarding.

Command flags (OPTIONS) in man pages have to date been in
haphazard order. Sometimes that order is sensible, e.g.,
most-important options first, but more often they're
just in arbitrary places. This makes life hard for users.
Here, I update the man-page-check Makefile script so it
checks and enforces alphabetical order in OPTIONS sections.
Then -- the hard part -- update all existing man pages to
conform to this requirement.
