050ae61817 [CI:DOCS] --volume: consistent wording
Make sure that the wording of mounting something _from_ the source
_into_ the destination is consistent.

3a9a7dcdcd Man pages: refactor common options: --volume
This one is a nightmare, because --volume has been edited
in four different files throughout the years (five if you
count podman-build, which I am not including in this PR).
Those edits have not always been done in sync.

The list of options was reordered 2022-06-28 by Giuseppe in #14734,
but only in podman-create and -run (not in podman-pod-*). No
explanation of why, but I'll assume he knew what he was doing,
and have accepted that for the reference copy.

There was also a big edit in #8519.

The "Propagation property...bind mounted" sentence first appeared
in pod-clone, in #14299 by cdoern, with no obvious source of where
it came from. I choose to include it in the reference copy.

The "**copy**" option seems to work in pod-create, so I'm including
it in the reference copy. Someone please yell loudly if this is
not the case.

The "disables SELinux separation for containers used in the build",
no idea, changed that to just "for the container/pod"

The "advanced users / overlay / upperdir / workdir" paragraph
makes zero sense to me, but hey, I assume it applies to all
the commands, so I put it in the reference copy.

Finally, there's still a mishmash of backticks, asterisks, underscores,
and even quotation marks. Someone is gonna have to perform major
cleanup on this one day, but at least it'll be in only one place.

aad29e759c health check: add on-failure actions
For systems that have extreme robustness requirements (edge devices,
particularly those in difficult to access environments), it is important
that applications continue running in all circumstances. When the
application fails, Podman must restart it automatically to provide this
robustness. Otherwise, these devices may require customer IT to
physically gain access to restart, which can be prohibitively difficult.

Add a new `--on-failure` flag that supports four actions:

- **none**: Take no action.

- **kill**: Kill the container.

- **restart**: Restart the container.  Do not combine the `restart`
               action with the `--restart` flag.  When running inside of
               a systemd unit, consider using the `kill` or `stop`
               action instead to make use of systemd's restart policy.

- **stop**: Stop the container.

To remain backwards compatible, **none** is the default action.

4675103c22 Man pages: refactor common options: --sysctl
As promised, harder and harder to review. Please take your time
with this one.

For IPC, I went with the list form. For net, I used the single-
sentence form instead of a one-element list.

The container/pod diffs are clumsy, sorry. Maybe it's time to
start thinking of a more flexible conditional mechanism, but
I'd really like to avoid that so I hope this is acceptable.

In the first sentence I went with 'namespaced' (final 'd') in
all instances. I also got rid of the 'new' in 'new pod' in
pod-clone.

40cd1c0ff5 Man pages: refactor common options: --device
The refactors are starting to get harder to review - sorry.

Here the differences are pretty small, mostly changes to the
"it is a combination" wording and some asteriskization.

The more significant diffs are that there are some Notes that
are pod- or container- or build-specific; I needed to move those
from the middle to the end, then keep them in the source files
themselves. I don't think this affects readability of the
resulting man pages, but your opinion may differ.

Last important thing: I included the /dev/fuse text in the
common option, which means it will now show up in podman-build
(it was not previously there). If this text is not applicable
to podman-build, please LMK ASAP so I can just move it back
to individual source files.

I did not even try to combine the podman-build one; that one

Two versions: one for container-related commands, one for pods.

The container one is easy: all versions matched, so I made no
changes.

The pod one is hard to review. I went with the pod-clone
version because the pod-create one looks suspicious: it
talks in terms of containers, not pods. It's possible
that I've got it wrong, and that these two cannot be
combined, so please review very carefully. I strongly
recommend using hack/markdown-preprocess-review for this one.

A NOP option. I chose the container word, of course, and the

74388fe75f Man pages: refactor common options: --pod-id-file
Much like --cidfile (#15414), --pod-id-file has two meanings.
One is used in pod-related commands, one in container ones.
Both meanings read the file, so the read/write split used
in --cidfile is not applicable here.

podman-pod-create keeps its --pod-id-file option because
that one cannot be refactored: that's the only command (now)
that writes a pod-id file.

Reviewable using hack/markdown-preprocess-review but I
did take some liberties with the #### args because they
were wrong. And, since I had to much with the description
text anyway (resulting in diffs), I also took the liberty
of cleaning up a double space.

46f31361f8 Man pages: refactor common options: --cidfile
There are two meanings: one writes a cidfile, the other reads.
Split into two .md files.

This can be reviewed with hack/markdown-preprocess-review .
The main differences you'll see are all in cidfile.read:

  1) I use the <<subcommand>> feature. This works nicely for
     kill, pause/unpause, and stop. It works less nicely for
     rm, because the man page will show "...and rm the container"
     (a human might prefer to see "REMOVE the container"). Given
     the benefit of this cleanup, I think this is a fine tradeoff.

  2) I choose to include the "multiple times" text even on man pages
     where it wasn't present before. I tested to make sure it works.

  3) The #### line I choose is IMHO the best one.

Minor differences:

  * I believe the "remove the container" text in podman-kill
    and podman-stop is a copy/paste error. This PR fixes it.

  * The only differences between the cidfile.write texts is
    the #### line (my version is best) and a final period.

fbe2bd87b0 [CI:DOCS] elaborate on image lookups of foreign platforms
After pulling/creating an image of a foreign platform, Podman will
happily use it when looking it up in the local storage and will not
pull down the image matching the host platform.

As discussed in #12682, the reasoning for it is Docker compatibility and
the fact that user already rely on the behavior.  While Podman is now
emitting a warning when an image is in use not matching the local
platform, the documentation was lacking that information.

f0e8640755 Man pages: refactor common options: authfile
Refactor the --authfile option.

My suggestion for review:
  1) run hack/markdown-preprocess-review and immediately Ctrl-Q to
     quit out of diffuse, which is completely unusable for this
     many files; then
  2) cd /tmp/markdown-preprocess-review.diffs/authfile
     - this is the directory created by the review script
  3) rm podman-image-sign* podman-log* podman-search.1.md.in
     - because they're essentially identical to podman-create
  4) rm podman-manifest-* podman-push.*
     - because they're 100% identical to podman-kube-play
  5) rm podman-kube-play*
     - because it's apart-from-whitespace identical to podman-build
       (use "wdiff" to confirm)
  6) rm podman-auto-update*
     - because that's the one I chose (hence == zzz-chosen.md)

(You should obviously run your own diff/cmp before rm, to confirm
my assertions about which files are identical).

After all that, you have a manageable number of files which
you can scan, read, diff against zzz-chosen.md, even run diffuse.

This option is IMHO the poster child for why we need this kind
of man page refactoring.
