   A great thread - I learned a lot about "zypper"   
   Additional Question: On Tumbleweed: A few times a week I get "Yast   
   Updates" which I understand as patches from the above discussion.  Today   
   they are up to 160.  Question: Suggest how often I should do "zypper dup"   
   in light of what the "Yast Updates" are telling me.
