Let's say you want to configure the interfaces yourself, what do you do?
I don't see the point of making scripts for configuring the interfaces when 
this has aldready been done.

I use dhcpcd on all my computers, and I also configure the interfaces on all my computers.
So I figure more people might have this same need, and also don't see the need for
creating loads of useless scripts, when this has basically been done for us already.

What do you mean? I've not been around for more than a couple of months, and
i've not been on the mailinglist all this time, so I'm not sure what you refer to

Thanks for the quick reply,
