I'm probably oversimplifying because I don't know much about overlays.

I'm not using layman at all but I am using a local overlay for mythtv.
From what I understand the 'overlayed' mythtv ebuild is responsible for
the overlay update though a script installed in /etc/portage/postsync.d/
which basically performs a 'git pull'. So unless there is a new git
snapshot upstream the modified ebuild will not get overwritten, correct?
