Whats new in Solaris Containers?
Starting in Solaris 10 10/08, Solaris Containers are automatically upgraded to the last system patches and packages when attaching to a new system. For example, if you detach a Solaris Container from one system and then attach it to a different physical system, the Container will automatically be upgraded to the same patches and packages that are on the new system. This allows for flexibility when performing rolling upgrades of systems and ensures consistency of systems when moving workloads. Also new in Solaris 10 10/08 is the ability for Solaris Containers to officially utilize a ZFS file system as their root. Upgrading a Solaris 10 system with ZFS-based roots for Containers is also supported.
