Are there any plans to support console client in a near future on R2? (what build?)
Note there's a difference between a "supported" platform where there's a cast-iron (and contractually backed if you get a maintenance agreement) guarantee that everything works, and the case where everything just works but the technical support people won't handle any problems that get raised. Asking whether it's supported is not the same thing as asking whether it works.
Actually, the console client should work just fine on R2. I wrote it, and I know of no reported problems with it on R2 in the GSS 2.5.1 release before I was laid off.
In actual fact, in the case of Windows Server 2008 R2, there is precisely one and only one GSS product feature that dosn't actually work, and that's not the console client - it's the "hot imaging" feature where the Ghost executable captures an image using the Volume Snapshot Services API. That feature would work just fine, but it's specifically blocked from working in the code by order of product management, because the Symantec System Recovery (formerly Backup Exec System Recovery, formerly LiveState Recovery, formerly PowerQuest V2i) product charges something like $1,000 per server for the same feature. Thus our product team wasn't permitted to call that API on server systems lest we undermine that product.
In versions of genuine Ghost prior to GSS 2.5, we were expressly forbidden by the VP in charge of our team from writing code which called the Volume Snapshot Services API call at all, for no other reason than to prevent us from competing with the ex-PowerQuest product. Having "hot imaging" available for workstations in GSS 2.5 was only possible due to a management change, so that we briefly had a VP who would allow us to actually add features useful to our customers (before the next VP cancelled development of the product outright), but even during that brief period of sunshine the PM for the ex-PowerQuest product fought a spirited rearguard action and was able to block us from making the feature available on server platforms.
