So now I got to binary pkgs and profiles, the profile is typically part of ebuild src tree/overlay
and a system using only binary pkgs does not need ebuild sources. How does one manage profiles
is this case?
Just sync an empty /usr/portage tree(sans profile) or is the a better way?

PS.
    emerge --depclean refuses to clean a system which is lagging behind, would it be possible for
    --depclean to go ahead anyway somehow? --dynamic-deps=n comes to mind.
