I use smart, myself. And in smart, I can "lock" a package and make sure 
that it doesn't go anyplace. I can even see in advance what "smart" is 
going to upgrade or downgrade or remove /before/ it happens.

No, don't /dump/ yum. But neither should you use it as your primary 
package updater. I keep it around for certain situations such as 
"repository reported unexpected size" that I've been seeing lately from 
some of the jpp repos.
