That is what the first 'if' should do.  Act as a filter.  So only if 
'zsh' had a dependency on a new yum or rpm would it go check for a new 
yum/rpm.  Otherwise it would just do the zsh update.

My perspective is from the user point of view.   If the user is 
upgrading to a new release let's say and the process goes along for 
quite a while and then decides to bomb out because the rpm version 
needed to be newer then the user becomes confused.  The software should 
take care of this.  So if any package in the whole update requires a 
newer yum/rpm then I think yum should go do that first.
