Ed Santiago c9c2f644da markdown-preprocess: cross-reference where opts are used 
In each options/foo.md, keep a list of where the option is used.
This will be valuable to anyone making future edits, and to
those reviewing those edits.

This may be a controversial commit, because those crossref lists
are autogenerated as a side effect of the script that reads them.
It definitely violates POLA. And one day, some kind person will
reconcile (e.g.) --label, using it in more man pages, and maybe
forget to git-commit the rewritten file, and CI will fail.

I think this is a tough tradeoff, but worth doing. Without this,
it's much too easy for someone to change an option file in a way
that renders it inapplicable/misleading for some podman commands.

--cgroupns=mode

Set the cgroup namespace mode for the container.

  • host: use the host's cgroup namespace inside the container.
  • container:id: join the namespace of the specified container.
  • private: create a new cgroup namespace.
  • ns:path: join the namespace at the specified path.

If the host uses cgroups v1, the default is set to host. On cgroups v2, the default is private.
