OpenSolaris: What Ubuntu wants to be when it grows up

Beauty is not only skin-deep. OpenSolaris employs the very same
enterprise-proven high-performance Solaris 10 kernel that powers the biggest
and baddest Sun boxes, and has the stability and monolithic scalability to
match, something that commodity Linux desktops and servers - while far more
stable and sprightly than Windows OSes - lack in comparison. In addition to
the Solaris 10 kernel, OpenSolaris makes use of Sun's advanced 128-bit
Zetabyte File System or ZFS, which permits "pooling" of storage on networked
Solaris-based systems, as well as Solaris 10's native "containers" for
OS-based high performance virtualization.
