Things like Project Indiana make it look a lot less like Solaris 9 and before do. Everything that is in Solaris 10 is in OpenSolaris plus a lot more - new package management system, new installer, crossbow (network interfaces), ... Eventually, OpenSolaris will become Solaris 11. The problem you will run into if you concentrate on Solaris 10 or OpenSolaris is that the majority of all Solaris systems out there is still running 9 and earlier. I get around quite a bit these days and my best guess is about 20% Solaris 10, 10% solaris 9 and 60% solaris 8 and 10% earlier releases. Solaris 8 isn't a good learning target because Solaris 8 x86 lacks drivers for almost everything. The differences between Solaris 8 and 9 aren't that great so you can save yourself a lot of trouble by just using Solaris 9 as the model for pre-10 Solaris. Peter.
