This looks like it can work, but note that it depends on some 9-CURRENT
sh(1) features:

* A printf(1) builtin, required to run without /usr. I don't see a sane
  way to avoid this.

* Some of the expansion changes, required for the line:
	iface="${line#\# resolv.conf from *}"
This can be avoided by changing that line to:
	iface=${line#\# resolv.conf from *}
