“One of the key features of Solaris 10 is its Zettabyte
File System (ZFS) that provides more storage flexibility and
scalability to Unix. For the past four years, however, ZFS was not
integrated into the deepest parts of the Solaris operating system
— a shortcoming that denied administrators access to its advanced
administration and recovery features.“That changed today, with the release of Solaris 10 update
10/08, which extends ZFS into the Solaris root. The update also
provides better integration support for Sun’s legacy Solaris 8
customers.”
