  Only one more question: what are the files in /var/spool/cron/crontabs used for ??? Are they the jobs for individual users? If so, why does my updatedb never get updated ? There is a job in there for me to updatedb and according to the man the syntax is correct.

Thanks for that clear and detailed explanation. Although I've been using Ubuntu for 2 years...and Linux for 3+ I never understood the relationship.
