[gentoo-portage-dev] Managing etc/* in an embbeded system

[Joakim Tjernlund]

We got an embedded gentoo system where we need to manage many conf files under /etc that we have
modified and should be under our control when an SW upgrade is performed.

Cloning every ebuild where we have modified its conf file(s) under /etc feels awkward so
I am looking for some other way to do this automatically during SW upgrade and I figured
this can not be an unique problem for us, so I wonder how other people have solved this problem?
Our customers will not use emerge directly and we will provide binary pkgs.

Any ideas welcome :)
