How to identify pairs that were packaged together versus pairs 
that were carelessly installed (by me) during different yum 
updates?
Should version numbers match in the former?
Must I manually scan pkg-by-pkg documentation or 'rpm -ql'?

Yup - I spent 2-3 hours yestermorning reading _all_ the 
4.4-upgrade-problems threads before posting to the list.  Saw the 
scripts for removing duplicates.  However, I don't remember 
seeing clearly a method for identifying packaged pairs from other 
duplicates.

Indeed, on a seperate run I appended the %{ARCH} format, and 
that's how I could tell that the kernel and gpg packages are 
version duplicates.

 	Thanks for the help.
