environment with very few resources, I need the functionality of
but don't want the
I know, because Simon told me before I started, that the way I've implemented it is ... suboptimal as it can block dnsmasq, but maybe Simon will have the time and the inclination to put that right?
Anyways, a patch to Simon is en route.
Update 2011-12-16: Simon has thankfully taken on the job of properly integrating the desired functionality into dnsmasq. :)
