Jeremy, What a swift response! You effectively addressed my question: is it possible that when I was using Gentoo/Linux few years ago (<2007), portage behaved the way you described even if the user was not appending the --update option? I might be wrong, but my memory suggests that on several machines with Gentoo/Linux installed from stage 1 I ended up using emerge world without the -u option and it always did the right thing (updating packages to the best version). Thank you in advance, Askar Bektassov (Аскар Бектасов)
