I'd also first like to see the examples. As I already tried to explain, during
a release (for all updates) the idea is to keep the APIs stable, therefore
there are no major changes in library versions and such. Updates are aimed at
fixing bugs, not at updating anything else significantly (besides adding
drivers, but that's irrelevant for our discussion).
Anyway, if this should really become necessary, I'd propose to aim at the
patching mechanism which we might get later this year. I.e. overlay the
current OSCAR release with an update-specific patch touching only the affected
packages.

??? I don't understand the question. But if it is: "why is the nomenclature
for distros and oscar paths different?" (eg. rhel vs. redhat-el-ws), then the
answer is my standard one: the scopes are different! There are many distros
which use the same OSCAR packages: centos, scientific linux
redhat-el-{as,ws,es}. It makes sense to have the distros with their original
name (don't want to mix updates of redhat with centos), but it doesn't make
sense to replicate unnecessarilly oscar packages which use the same APIs
(because the APIs are the same across all rhel compatile distros).
Not sure I answered the questions...

Erich
