Invalid: system requires virtual/bootloader. When installing Gentoo, Grub isn't per default installed. You still need to install it (or LILO) manually. Afterwards, GRUB (or LILO) will fill the role of virtual/bootloader and will therefor be listed. But as long as you don't explicitly emerge GRUB or LILO, it will not show up in system. /usr/portage/profiles/$YOUR_PROFILE/packages
