I see stuff in that subdirectory related to overlays I have enabled via
layman, and ebuilds provided by those overlays, even when I'm _not_
using these ebuilds but the ebuilds for the same packages provided by
gentoo itself.  Or so I hope - for all such overlays I've masked */* and
only unmasked the 1 or 2 particular packages I need, which aren't in
gentoo.

The true reason the directory bothers me is its permissions, and those
of the files inside.  They seem to be created as portage:portage, 0660.
Why is root:root 0640 not good enough for them?  Does that mean some
part of portage runs setuid/setgid to the portage user/group?
