I'll commit it after the doc tree slush.

I'd change "a single place" in the commit message to "ifconfig(8)". Other than that and the change above, LGTM.

Not sure what the right markup for this is , but needs a more specific pointer than a 2000+ lines manual page.

Don't need to be root for list scan, unless that changed in 13

I don't think that we have an asciidoc macro for that. I'll point to "list scan" as you say. Thanks!

Hmm, that's a good point but we are using # consistently throughout the chapter. I'm not convinced if changing some of those prompts to % or $ is helpful to the reader. I'll keep # for consistency for now.
