Re: [CentOS] when is the o.s. considered to be at a certain minor version? Or, is it safe to apply only certain package updates from the next release version?
If you dig through the Red Hat site enough, you will find that there is no Red Hat Enterprise Linux 6.2. There is only RHEL6. 5.x,6.x are NOT defined outside of what is on the isos. So far as I know, it applies to CentOS. This is not Solaris/AIX/HPUX/Windows. There are no defined releases or 'service packs' which guarantee a particular _set_ of minor versions to be present. .

Would you agree with Minor versions are snapshots in time when all of the latest updates, and a batch of new ones, are merged into a new base repo, the updates repo is emptied, and new installation media are generated?

on 5/10/2012 1:14 PM Jon Detert spake the following: Two related questions about the minor release numbers (e.g. the 'x' in 5.x or 6.x) : 1) What constitutes the o.s. being at a particluar minor release? Typically, when you install you are getting a package set available from a specific minor release number. But what minor release is the o.s. at if I just update the centos-release package, and no other package? Typically, a 'yum update' is said to take your whole package set to the latest minor release. But what minor release is the o.s. if you just update certain packages (instead of taking all avaailable updates)? 2) Can I apply package updates made in a minor release greater than my current release without detriment to the integrity of the o.s.? E.g. Suppose all my packages are at versions delivered in v5.6. Suppose also, that I have a package xyz installed, and that an update to it was made available in v5.8. Can I upgrade xyz to the updated version from 5.8 without updating other packages (except for any dependencies xyz has) to the versions available in v5.8? Thanks, The minor versions are only snapshots in time when install media is re-generated... There is no good reason to stay on previous minor versions... There is really only a 5 version or a 6 version... Staying with older packages will only give you security problems... ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Minor versions also introduce newer kernels (hardware support) and some changes in packages that are not done during regular update releases. Certain technological previews are also introduced and so on. If you were right, then all those packages would just be shoved into updates repository. The difference between Fedora releases and RHEL/CentOS minor version is ability to upgrade to next minor version fluidly, without loosing kABI/ABI compatibility. -- Ljubomir Ljubojevic (Love is in the Air) PL Computers Serbia, Europe Google is the Mother, Google is the Father, and traceroute is your trusty Spiderman...

Those 'newer kernels' are sub-versions of the same x.y.z kernel originally released. 6.2 plus updates is currently 2.6.32-220, it was originally 2.6.32, and 6.anythign will remain 2.6.32, only the -xxx will change. Yes, sometimes new hardware support is added. Those technological previews are in the form of additional packages. Don't want them?

If you were right, then all those packages would just be shoved into updates repository. They pretty much are. You should be able to 'yum update' any specific package to any newer rev. regardless of the revisions of the rest of the system, and the rpm dependencies will pull anything else that must be updated to match.

They coincide with batches of less critical fixes so if you are installing a new system it would make sense to install from the new media instead of the huge update from an earlier version.
