@cgwalters @dustymabe PTAL

Should I also add the --version?

[dustymabe]

This may be a bad idea but is it possible to "collect" all options that atomic cli doesn't know about and simply pass them through to rpm-ostree. If it's a bad option rpm-ostree will complain about it. Would this be better than having to maintain the options in two places?

If this is a good idea then it is also something we could implement down the road and accept this PR the way it is for now.

[cgwalters]

I would lean a bit towards maybe only supporting the "common" options like --allow-downgrade - people who are using --sysroot are doing pretty advanced things.

That said, no objections to the patch as is too.

(Long term, I think we could support scraping the options dynamically, or just use rpm-ostree as a shared library)

[rhatdan]

I took a quick look to see if there was a way to handle options that the command did not know about, but I found nothing.

We could add something like example something like this.

atomic host upgrade -- --foobar

And then pass the additional arguments to the command?

This would not show in atomic host upgrade --help
though.

Ok I am going to merge this patch. Should handle both cases.
