keeping up to date with cron

[Dan Rue]

Hey Gang, 
I am somewhat new to the FreeBSD stuff.  After getting used to the cvsup
way of life, I added this to my crontab:

# Package database maintaince
25      2       *       *       *       root    /usr/local/bin/cvsup -g -L 2 /root/cvsup/ports-supfile && /usr/local/sbin /portsdb -uU
0       1       *       *       6       root    /usr/local/sbin/pkgdb -aF
 
# Should probably do this manually from time to time
#0      4       *       *       6       root /usr/local/sbin/portupgrade -aRy


Note that I don't actually run portupgrade from cron anymore.  Any
suggestions on better flags or ways of doing any of these tasks?  What
do you all have in your crons?  Note that this is a desktop system, not
a production server.  But what if it was a production server?  Shuold I
do anything differently?

tia,
