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.

--cpu-rt-runtime=microseconds

Limit the CPU real-time runtime in microseconds.

Limit the containers Real Time CPU usage. This option tells the kernel to limit the amount of time in a given CPU period Real Time tasks may consume. Ex: Period of 1,000,000us and Runtime of 950,000us means that this container could consume 95% of available CPU and leave the remaining 5% to normal priority tasks.

The sum of all runtimes across containers cannot exceed the amount allotted to the parent cgroup.

This option is only supported on cgroups V1 rootful systems.
