    I think the best way is to create a shell script, like this:

    #!/bin/sh
    /usr/local/sbin/portsnap cron && \
    /usr/local/sbin/portsnap update && \
    /usr/local/sbin/portsdb -uUF && \
    /usr/local/sbin/portupgrade -aF && \
    /usr/local/sbin/portsclean -DP

    and run it at an hour, when you're most unlikely to
    perform any kind of port upgrading. As portsnap
    manpage warns, if both portsnap (in the process
    of update) and portupgrade ever happen to access
    the same directory at once, it might ruin your
    ports tree. You'll have to do "portsnap extract"
    after that. You can leave out portsclean and run
    it manually, because it can create some load
    (which is not desirable on a production server).

    I run this script daily at 8-9 in the morning (I usually
    start messing with servers after 11). It never failed,
    and it always keeps everything up-to-date.
