After postponed to release on March, we will be getting new Opensolaris version in the next few days. It is Opensolaris 2010.05. This is what i am waiting for. There are plenty of new softwares and tools. For administrators, many new tools have been added such as Oracle Solaris 10 Containers, Triple-Parity RAID with ZFS, Splitting a ZFS zpool, Save space with ZFS Deduplication, User and Group Quotas with ZFS.
