If I were to continue to use portsnap, which arguments can I safely
add to /etc/crontab? I know "portsnap cron" should be safe, but if I
want to completely automate the update process (not for installing
packages, but for keeping the ports tree, database, and indexes
current), should I also add an entry for "portsnap update" and
"portsdb -uUF"?

Would you also recommend cron entries for these two commands?

I used to use a cron job to run cvsup, and I'd like to implement a
better, more complete automated solution, so I don't tangle up my
system's packages and dependencies again.
