Well, sometimes it's just nomenclature :) With yum/rpm orphans are packages
that no longer reside in an available repository so ALL locally installed
packages will be in that list.
After an upgrade you want to use the --problems and --dupes options to do
some housekeeping.
Sometimes yum remove seems to know what were installed as dependants other

Well, it's basically that it works in one direction only. If you install a
-devel package it will install all the required base packages, if you try
to remove the -devel package it doesn't know you don't need the base
packages anymore, but if you try to remove any of the base packages, it
MUST remove the -devel package or there will be dependency issues.
