suggest just to be clear that you're talking about named and not anonymous volumes

LGTM. Totally agree with the decision. I made the very same choice in the WIP work for podman-cp. It currently would create a path on the container if doesn't exist and I find this kind of magic dangerous - as you said, a typo would be masked and deployments can break in hard to debug ways.
We differ from Docker, in that we do not create the source directory in a --volume mount if it does not exists. We return an error. We do not believe that a `typo` from the user should cause a directory to be created and silently ignored by Podman. Fixes: containers#8513 Signed-off-by: Daniel J Walsh <[email protected]>

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 containers#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 containers#8519. The "Propagation property...bind mounted" sentence first appeared in pod-clone, in containers#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. Signed-off-by: Ed Santiago <[email protected]>
