SCCM SP2, R2, R3, do you get confused too?
Yesterday I have installed SP2 on my Lab system, no problem there.
It just got me thinking about this: if today you would need to install a new SCCM system, there are already a couple of installs to do, by preference start with a ‘SCCM 2007 with SP1′ disc, then install SP2, then install R2 if you need those features also.
The R2 and coming R3 are feature packs (or addons if you want) which are not part of the basic SCCM product, so they will always have to be installed separately if you need those features. That is the difference with SP2, which is a service pack for the basic product (and applies to the site, clients and admin consoles)
As it seems during next month a new ‘SCCM 2007 with SP2′ disc will be released, so that is one setup less to do…
