[CentOS] Yum-cron

Ok, I've just had issues this morning, and went and *looked*. I can see a
yum-cron running monthly, sure. Running weekly, I guess. Running daily?
Why?

And there is *NO* reason whatever for a "yum-hourly*. None. This is
CentOS, not ubuntu-snapshot-of-the-moment.

I don't know if this is from upstream or not, but it's wrong. I mean, even
Redmond only pushes out patches once or twice a month, except for critical
fixes.,,,.
