I have read multipe messages here from people upgrading from 5.0 to 5.1, presumably using "yum update" to do the deed.

When I do "yum update" on my (I think) fully updated Centos 5 system I get no updates.

Am I just being impatient (i.e., the updates haven't yet been pushed out) or am I somehow missing them?

well, have you changed anything in the default centos shipped /etc/yum.repos.d/CentOS-Base.repo ?

and, check : rpm -qa --last | head and : rpm -q centos-release

perhaps you are already on 5.1 ?

Hmm.

# rpm -q centos-release centos-release-5-1.0.el5.centos.1

and:

so, perhaps I did get the update, since the first of those 2 cmds shows 5.1. But I don't remember getting a huge bolus of updates, which is what I would have expected to constitute a 5.0==>5.1 transition.

Probably I was further confused by /etc/redhat-release:

# cat /etc/redhat-release CentOS release 5 (Final)

which apparently (based on someother postings) a bug.

Thanks for the reply!

Try

yum upgrade

instead of yum update.

wont make much of a difference in this case, upgrade is just an alias of update with the --obsoletes flag

check your syslog, it will indicate what was installed and when.

Which is what the system is. For anyone who stays on the update path, it will stay at 5 since that is the distro you are running. If you are new to the whole idea of the EL process, it might be a good idea to read up on what and how update cycles work and how the z-series is going to kick in for centos-5

So there's been a change since Centos 4, then. (I'm fine with that, I just didn't know it...). From my Centos4 box at work:

$ cat /etc/redhat-release CentOS release 4.5 (Final)

Said machine was instaleld at Centos4 and kept updated with YUM.

Thanks for all the info!

yup, bit of a change with the upstream people adopting this whole z-series thing, wherein they will now maintain branches for 5.1 even when 5.2 is released.

over the next day or so, I shall try and get a document that explains this whole thing.

Before CentOS 5 x86, I was using Scientific Linux 4 and they were keeping 4.x trees (e.g. 4.0, 4.1 etc) and for having an upgrade to the latest tree automatically, we were using a plug in or something (installed as an rpm). Those without that rpm were kept to their release (tree) and were getting only the updates for their release (4.0, 4.1 and so on). At the same time, I remember (either saw at the CentOS site, or someone mentioned it in the SL mailing list), that CentOS was keeping up only with the latest release (tree) of Red Hat EL4.

So I am not sure the tree issue (x.y) did not exit before. I haven't understood the new x.y.z scheme though.

For a minimal install, there were surprisingly few new packages for 5.0 => 5.1. Looking at my /var/log/yum.log, I only had 90 packages updated or installed.Total installed packages now is 277.
