Well ... if you look, WE use a 5 and not a 5.0 or a 5.1 in our
CentOS-Base.repo
5 initially contains 5.0 ... and will contain 5.1.
SO ... if you use the 5 and not 5.0 or 5.1 then you will be set.
We do remove 5.0 when we add 5.1 (and 5.0 goes to our vault ... at
http://vault.centos.org/.
So ... if you sync down 5.0 ... I would sync down 5 and 5.0 and 5.1 and
use 5 as the update source not 5.0 or 5.1. If you are using $releasever
then you are already using 5 and not 5.0.
Then when we shift, it will be seemless (as long as you have Base and
Updates both turned on).
We DO NOT put all updates since the beginning into updates, it is ONLY
updates that to the CURRENT branch. However, base+updates of the
current branch == all the latest RPMS, so a yum update against 5.1
base+updates from any other 5x will get you totally updated (once it is
released and we have set 5.1 to the default).

It's simply. All things from 5.0 to 5.1 will be done automatically

If you remove the point release numbers from your update paths you do
not need the old versions. If you really need the old updates use
http://vault.centos.org/
From http://mirror.centos.org/centos-4/4.4/readme
This directory (and version of CentOS) is depreciated. For normal
users,
you should use /4/ and not /4.4/ in your path. Please see this FAQ
concerning the CentOS release scheme:
http://www.centos.org/modules/smartfaq/faq.php?faqid=34
If you know what you are doing, and absolutely want to remain at the 4.4
level, go to http://vault.centos.org/ for packages.
To simplfy our yum configuration I disable all the repo files in
/etc/yum.repos.d and call the yum configuration from a local web server
in yum.conf by using the include statement. One change on the web server
changes the yum configuration on all CentOS machines.
In the yum.conf I add
# Site yum files
include=http://ourserver.ourdomain.com/centos/yum/centos.repo
include=http://ourserver.ourdomain.com/centos/yum/centos-updates.repo
The centos.repo looks like this,
[base]
name=CentOS-$releasever - Base
baseurl=http://ourserver.ourdomain.com/centos/$releasever/os/$basearch/
enabled=1
gpgcheck=1
And the centos-updates.repo looks like this,
[updates-released]
name=CentOS-$releasever - Updates
baseurl=http://ourserver.ourdomain.com/centos/$releasever/updates/$basea
rch/
enabled=1
gpgcheck=1
[custom-repo]
name=CentOS-$releasever - Custom-rpms
baseurl=http://ourserver.ourdomain.com/centos/$releasever/customrepo/
enabled=1
gpgcheck=1
Hope this helps.

If you install a Centos 4.0 now you can 'yum update' and you'll end up
current with 4.5. I think this works because the [base] repository
floats with the symlinks to point at one containing the updated versions
of everything at the point release time. If you are talking about
mirroring the contents you'll have to mirror the symlinked directory.

If installed with 4.0, and run a 'yum upgrade' will
end up with 4.5 -- then, what are the repos configured
for yum? Are the repos the following and ONLY the
following (excluding custom ones)?
1, 4.0 base OS distro
2, 4 base OS distro (symbolic link pointing to 4.5)
3, 4 updates (symbolic link pointing to
.../4/updates/..., which means updates since 4.5
sub-release)
Is the above right? or you have even omitted #1 (4.0
base OS distro repo)? Thanks.

in that case you will need to find the updates in the 5.1/os/ repo as
well and put it yourself into the updates/ directory, which will be a
waste of time, network bandwidth and resources. You are going to be much
better off just installing 5.1 from the future and using that.
For the machines you have 5.0 on, just run yum against the 5.1/os/ and
5.1/updates/ repo, and they will also move to 5.1. Note, the [os] repo
also needs to be from 5.1 and not from 5.0 when you run the yum update
on the 5.0 installed machines. other wise you *will* loose updates.
Currently I can not do it, because on Internet Centos
Mirror Sites, the centos/{4,5}/updates/ are in fact
symbolic links to
centos/{4,5}.latest_update_snapshot_release/updates/
and contains update RPMS ONLY SINCE the relase date
{4,5}.}.latest_update_snapshot_release. But what I
like to have is a accumulated updates repository since
{4,5}.0 release date.
you are trying to solve the wrong problem. I suggest you take a few
minutes and work out exactly how the /5/ and /4/ symbolic links are
handled on the mirror.centos.org network, and setup something similar
for yourself as well.
Has any one done the above? If so, how is that
working? or there is no need to do do it because there
I dont know how you install the machines, but i think its a fair guess
that just reimaging the install process with new installer images for
each point release, will be a lot less work than what you are doing at
the moment.

With Centos 3.x you could easily pull things through a caching proxy by setting http_proxy in the environment from the command like: http_proxy=myproxy.mydomain.com yum update. and any number of machines at a location would only have to download a needed file once (assuming your proxy is configured to cache large files).

and used it for my 900+ boxes's daily upgrade already.
The repository is synchronized with official Internet

My major concerns is: After the 5.1 is released, the

(.../centos/5.1/updates/{SRPMS,i386,x86_64}/...) may
change to contain only updates for 5.1
snapshot/release, not updates since 5.0. If so, then
all my Centos 5.0 boxes will suffer.
I have the serious concern because most Centos Mirror
sites on Internet ONLY keep the updates for latest
release/snapshot, not holds updates since the
base(3.0, 4.0, 5.0 etc) release. This seems like a big
problem if we would like to install from base|initial
release (3.0, 4.0, 5.0) continuously and then use a
single up-to-date update/ repository to upgrade
machines to current level.
For example, at Stanford's Centos 4 mirror site, only
4.5 is mirrored while all the other
4.0/4.1/4.2/4.3/4.4 are not. and in the updates/
directory only updates for 4.5 are kept there. If the
same is true for all other sites honoring 5.0 series,
then I think I will definitely get screwed If I tried
to keep on using base 5.0 and daily synced updates/

Any mirror sites hold updates since base release? Or I
have to keep on adding more repositories to yum's
configuration? 5.0 distro, 5.0 updates, 5.1 distro,
5.1 updates, 5.2 distro, 5.2 updates. etc. If so, then
it is too low-performanced and erro-prone.
