[oe] how to change system files

[Jaap de Jong]

Hi All,

annoying question here...

What is the best way to change files like /etc/network/interfaces?
I have about 5 files or so that already are supplied by (default) 
packages; they are not in 1 package.
I would like to have them in one package that I own so that I can easily 
update them, but this is not necessary.
Is overlays the way to go?

Thanks!
Jaap
