I think initially I was initially expecting to but ended up not needing
to.

I will assume you would also prefer "setup_${firmware}_pxeboot_local" to
become "setup_pxeboot_local_${firmware}" (rather than "setup_pxeboot_
${firmware}_local").

Good idea.

Do you think setup_pxeboot maybe ought to be setup_pxeboot_di or
something along those lines?
