quick question on yum

[geisj at pagestation.com (Jerry Geis)]

I think I saw where up2date is going away (perhaps browsing FC5 new and 
changed items)

"yum update" will ask me if it wants to proceed. I have not seen a way 
to not have
the prompt for Y/N? Is there a way to not prompt and just go ahead and 
do the update.

Thanks,

Jerry
