The crontabs on RHEL seem to be duplicated in two places,
/var/spool/cron. I've checked, and neither of these are simlinks to the other, and neither are any of the crons contained in either location.
I guess my most important question is this, which of these two is the authoritative location? If I were to edit a file in only one of these two, which one would I have to make my edit in to get it to execute?
