during my usual packages upgrade routine a new package appeared on the list of the ones that should be updated: centos-release (6-4.el6.centos.10). I would like to know if this installs a new kernel as my Cloud provider excluded from the yum.conf file the kernel upgrades

Yes, this installs the new EL6.4 kernel version - 2.6.32-358.0.1.el6 and newer.

CentOS follows the Red Hat release cycle. The minor version of CentOS was bumped from version 6.3 to 6.4 last week.

yum update and yum upgrade would both push you to version 6.4 at this point.

  • My current version is Centos 6.3 final, should I use yum upgrade or yum update? What's the difference? – Stefano Mar 12 '13 at 19:04

    I think you are wrong. CentOS-release does not update the kernel. the kernel RPM updates the kernel – thanosk Mar 12 '13 at 19:27
  • The release updates the target OS revision. The OS revision dictates the kernel version. If the question is whether an update from EL 6.3 to EL6.4 includes a kernel upgrade, the answer is yes. – ewwhite Mar 12 '13 at 21:09

No that particular RPM just updates certain files for the 6.4 version of CentOS

#repoquery -l centos-release

/etc/centos-release
/etc/issue
/etc/issue.net
/etc/pki/rpm-gpg
/etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6
/etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-Debug-6
/etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-Security-6
/etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-Testing-6
/etc/redhat-release
/etc/rpm/macros.dist
/etc/system-release
/etc/system-release-cpe
/etc/yum.repos.d/CentOS-Base.repo
/etc/yum.repos.d/CentOS-Debuginfo.repo
/etc/yum.repos.d/CentOS-Media.repo
/etc/yum.repos.d/CentOS-Vault.repo
/usr/share/doc/centos-release-6
/usr/share/doc/centos-release-6/EULA
/usr/share/doc/centos-release-6/GPL
/usr/share/doc/redhat-release

the kernel is a different RPM
