Question about differences in RHEL 4.1 and CentOS 4.1 organization.
There is no such thing as RHEL 4.1. Red Hat keeps the version the same and just provides updates. Every so often, a new set of ISOs is spun, and called RHEL 4 Update x (where x increments).
How do you determine what packages were "regular" updates, and which packages were part of U1?
For RHEL, they are all "regular" updates.
And for CentOS as well ... the x in 4.x relates to the update number.
There is a 4/ symlink that points to the current tree (4.0) ... the 4/ symlink will shift from 4.0 to 4.1 when all the 4.0 arches (ia64, x86_64, i386) have a fully functional (and tested) 4.1 tree.
We release the Security (RHSA) updates for update X as soon as they come out, then we take the Enhancement (RHEA) updates and Bugfix (RHBA) updates and build the new trees, test them, then release them. When all the trees for the whole release are done, we shift the symlink.
That should happen in the next couple days for both 3.5 and 4.1.
So CentOS 4 is the release and 4.1 means update 1.
So, you can manually point to 4.1 now (if you use ia64 or i386) or wait until we shift the link later after the x86_64 tree is live.
I tried to explain in the availability announcement: http://lists.centos.org/pipermail/centos-announce/2005-June/000310.html
(maybe not such a good job of explaining) :)
CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
Does it mean that if I installed CentOS 4.0, I have to do a yum upgrade on the 4.0 tree in order to have the last version of all installed packages then a yum upgrade on the 4.1 tree ? Or is it possible to do a yum upgrade directly on the 4.1 tree and it will upgrade all the installed packages ?
If it is the first question which list the correct steps, how are made the updates if I install after a period a package from my CentOS 4.0 iso and then do a yum upgrade on the 4.1 tree? (Perhaps that there was an update in the 4.0 updates tree. Or do I miss something?)
One more question : Is it better to do yum update or yum upgrade if I want only the already installed packages to be updated ?
Thank you for your help,
