selections (think "world")
from my laptops, downloaded and installed around 1400 packages in a bit over
5 hours.
This included both libreoffice (the default) and openoffice (from the
selections), apache,
gimp, on and on, and would surely have taken a week or so under Gentoo.

Today, I port over my apache configuration and my embarrassing downtime is
ended.
