I wrote some code to support DNS zonetransfers in host completion.
It's a simple replacement for _hosts and it is not quite perfect yet.
You have to put a "search domain.com" line into /etc/resolv.conf and
need to have the "host" utility installed on your system.
Please let me know, what you think about it.
Also, I have two questions: How can I make libc calls directly from the
shell? You guess it: gethostbyname(2). Would it be possible to
substitute the awk usage with zsh parameter expansion?
please use reply-to, I'm not on the list.
