Project Indiana
I'll hazard an educated guess here. Project Indiana is Ian Murdock's plan to help Linux developers feel more at home in the Solaris userland, by making the userland more Linuxy. This probably entails a revamp (or at least augmentation) of Solaris's packaging systems with something like Aptitude, followed by meta-packages for things like getting a complete GNU userland. Knowing Sun, however, there will likely be some extra sauce to make it ten times more exciting than that.
