Updating a headless server to fc6 ?

[Kim Lux]

I've got a headless server that I use ssh and such to do everything on.

Is there an easy surefire way to update the server to fc6 without
putting a monitor and keyboard on ?   

Can this be done with yum ?   I remember people talking about doing yum
updates in the past but I believe there was some controversy about
whether it was a legitimate method.  Comments ?
