The normal update mechanism should bring your machine up to 5.1 unless you've taken actionto lock it to the 5.0 release.When I installed this box, 5.1 wasn't out yet.. And, no I haven't taken any kind of action to lock it to 5.0.I have run "yum update" a few times, but I don't see any signs of it wanting to upgrade to 5.1..The upgrade to 5.1 is seamless. Your actual version (the replacement for "$releasever" in the URL in the yum config file) is "5", not "5.0", which will always track the latest release. Sounds like the kernel version(currently kernel-2.6.18-53.1.14.el5) is not what is causing your problem.
Let me relate this to Windows :DCentOS-5.1 and 5.2 and 5.3 are like XP, XP Service Pack 1, and XP Service Pack 2.
====================================================================So you are always running CentOS-5 ... it is just a different state of being updated.
Neither the upstream provider nor CentOS recommends that you UPGRADE your install from one MAJOR version to another (ie CentOS-4.x to CentOS-5.x):
https://www.redhat.com/archives/rhelv5-beta-list/2008-March/msg00005.htmlThe upstream provider (and CentOS) recommend that you instead backup your data and reinstall your os as a new install, THEN restore your data and configure:
http://www.centos.org/docs/5/html/5.1/Installation_Guide/ch23s01.html HOWEVER ...if you do upgrade from 3.x (where $releasever is 3) to CentOS-4.x or CentOS-5.x then the $releasever will change to 4 or 5 as appropiate. In CentOS, $releasever is controlled by the VERSION (and not the RELEASE) of the centos-release package.
