But this doesn't work if two different people in the same building do
updates since they won't know the other's choice of order. Plus it is
painful to have to edit files on every machine to make something happen
that should work by default. I liked the Centos 3.x approach with rrdns
much better since all requests had the same URL even when served by
different sites.
