Hi all - First the boilerplate: On centos-release.x86_64 7-0.1406.el7.centos.2.3 [root at localhost x86_64]# uname -a Linux localhost.localdomain 3.10.0-123.el7.x86_64 #1 SMP Mon Jun 30 12:09:22 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux [root at localhost x86_64]# rpm -qa kernel\* | sort kernel-3.10.0-123.el7.x86_64 kernel-devel-3.10.0-123.el7.x86_64 kernel-headers-3.10.0-123.el7.x86_64 kernel-tools-3.10.0-123.el7.x86_64 kernel-tools-libs-3.10.0-123.el7.x86_64 I built kernel-3.10.0-229.7.2.el7, successfully to appearances. But on installing the new rpms I receive a couple dozen messages like these: [root at localhost x86_64]# rpm -ivh kernel-*.rpm Preparing... ################################# [100%] file /usr/lib64/libcpupower.so.0.0.0 from install of kernel-tools-libs-3.10.0-229.7.2.el7.centos.local.x86_64 conflicts with file from package kernel-tools-libs-3.10.0-123.el7.x86_64 file /usr/bin/cpupower from install of kernel-tools-3.10.0-229.7.2.el7.centos.local.x86_64 conflicts with file from package kernel-tools-3.10.0-123.el7.x86_64 Have I missed a step? Maybe something specific to 7 or different from 6? Thanks.....Nick
