@nalind, I'm teaching myself Buildah and other container tools like crun, podman in the little free time I get these days (newborn at home). I’ve started by comparing the man‑page documentation with the actual code. I hope it’s okay if I open small documentation PRs whenever I come across something unclear or inconsistent.

Please let me know if small PRs like this end up causing any inconvenience. It is not my intention.

LGTM, thanks!

I'll admit it did raise an eyebrow - usually if we don't catch things like this in the PR that adds the text to the man page, they only get caught when a maintainer is in there doing something else, but you've allayed my concerns. Thanks again, and congrats!

Looks like the commit validation test is getting confused by the commit log not putting a blank line between docs: fix typo dns-option and the Signed-off-by, treating them as one subject line that's been wrapped instead of a subject and a longer description.

LGTM
and nice Eagle Eye on this one.
