Hello,
I've created a small patch that was discussed in this bugrepport,
https://bugzilla.gnome.org/show_bug.cgi?id=563654.
It's a tiny patch that adds a dispatcher event on the dhcp_renew state
and updates the manpage accordingly.
This is useful if you want to for e.g. use nsupdate to dynamicly update
dns-entries. You probably want to do that everytime a lease is renewed.
What you also could do (what i used to) is to use a cron-job that runs
with tighter interval than the dns-server uses to hold entries, however
that method is quite messy and not preferred.
I'm no programmer so go easy on me if I missunderstood anything in the
coding part. (one line) :)
/Patrik Martinsson,
