Well the upgrade is NOT reinstalling all that was erased: # yum upgrade Installing: kernel i686 2.6.32-431.20.3.el6 updates 26 M Installing for dependencies: kernel-firmware noarch 2.6.32-431.20.3.el6 updates 13 M Transaction Summary =========================================================================================================== Install 2 Package(s) So looks like I will have to do all the others step by step.
