Dear Fog_Watch,

I'm a Gentoo user, too. And I'm working (completely all) with NFS and shared portage trees, also. Nevertheless, i'm don't using unpriv'ged containers or shifting, yet.

But don't think that Gentoo need to have the user/group of the portage tree to be "portage:portage" for the purpose to run a ebuild. This will be a requirement for portage sync operations, of corse. But this ones, you probably want to run on the host, i think. Maybe you should even bind-mount it read-only to your containers. 

You need to have write access to the distfiles directory (and packages directory -- if you use it). You may hold this ones outside the portage directory by defining variables; please refer to  man make.conf  .
