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.

--device-cgroup-rule="type major:minor mode"

Add a rule to the cgroup allowed devices list. The rule is expected to be in the format specified in the Linux kernel documentation (Documentation/cgroup-v1/devices.txt): - type: a (all), c (char), or b (block); - major and minor: either a number, or * for all; - mode: a composition of r (read), w (write), and m (mknod(2)).
