There are differences in the upstream release for Client and Server
(much like the difference between AS, ES, WS, Red Hat Desktop, etc).  We
handled this in CentOS-3 and CentOS-4 by just releasing the AS package
set and it contains all the other subsets.

It is slightly different now, however, as there are separate yum
repositories (and directories) for Server, Client, VM, Cluster*, etc. on
the EL5 Beta2 CDs (much like CentOS has extras, centosplus, etc. :P).

In a yum tree on the server this is not too hard, links can be created
to connect the packages that are the same and all can co-exist in one

(that might also work OK for the Binary DVD too ... we might be able to
fit all the packages on the DVD in separate repos/dirs and keep it under

As far as I know, ln -s or hardlinks will not translate to size savings
(or even work) on an iso9660 CD ... therefore it seems that we may have
to either:

1.  Combine all the packages into a single repository (CentOS or Release
or Server, etc.)  This is similar to what we currently do on 3 and 4
now, with all the AS packages included.


2. Release a CD set with Server and Client (and all the other repos on
it ... showing everything) ... no idea how much space that takes yet or
if it is doable.  I would think (if we can't use links) that this set
would be 6-9 discs in size.


3. Release a Client and Server CD, and a Client and Server DVD ... but
put everything in one yum tree with a Client and Server and all the
other dirs/repos under that tree. (I would imagine that each set would
be 4-5 discs in size)

I think 3 is the way that makes the most sense ... it also requires the
most disk space and bandwidth ... and requires the most maintenance.
Option 1 is less disk space, in keeping with what we currently do, BUT
creates an install that is not much like upstream.

Once installed, either of these methods becomes the same as all yum
repos should be enabled by default, unless we have a centOS-release-
client and centOS-release-server ... so that if you install client, you
get only client repos by default and for server, only server repos by
default .... and you could enable the others too manually on each if you

The developers need to play with all these ideas and test several things
before we can even smartly discuss these options.

Once we have a better idea what this entails, we can discuss it further.

I'm sure Oracle is waiting on our decision, so we should make it soon :P
