one 'head' node, rather than just pointyhat itself. Constants are factored out into installation-specific files known as portbuild/conf/server.conf and portbuild/conf/client.conf. There is only one server.conf file. Individual <arch> directories may have their own client.conf files, or may symlink to ../conf/client.conf. This first set of files only gets the *.conf files and some cleanup. Feature safe: yes
