Descargar el arbol de ports "fetch", se descomprime "extract" (se ejecuta la primera vez)
# portsnap fetch extract
Ahora para manterner el arbol de ports actualizado, se ejecuta siempre
# portsnap fetch update
Esta ultima linea se puede agregar al cron para que diario actualice los ports, en /etc/crontab se agrega una linea como esta

Una nota muy importante en caso de querer editar manualmente los archivos del DNS http://forums.freebsd.org/showthread.php?t=33849
"Note about editing dynamic zones manually
If you have to edit the zone files of dynamic zones manually while the DNS server is running, you’ll have to freeze the zones with # rndc freeze <myzone> before editing and unfreeze them with # rndc thaw <myzone> after editing. This is because named(8) has internal state information and external journal files attached to dynamic zones that have to be kept in sync with the zone files."
