Want to keep your opensolaris on the “edge” of developments? Most of the experience i have had is that the “dev” repository contains mainly stable releases that are being held until the next official release (every 6 months).

Add the dev repository URL and give it a name.

NOTE: The name cannot contain any spaces!
