It is safer to copy the world file to /etc/portage/sets/¹ and then emerge the set. This way portage won't think that the packages are already installed. So you could copy it to /etc/portage/sets/minimal-install and install it with emerge -a @minimal-install. Kind regards, tastytea ¹ <https://wiki.gentoo.org/wiki//etc/portage/sets>
