ONJava has an article by Sam Hiser:
While Java is important to JDS, there should be no mistaking that JDS is a complete and thoroughgoing Linux distribution. In fact, JDS is based on Novell’s SuSE Linux distro, employs the GNOME user interface, and carries a complete selection of desktop applications. Many, if not most, of JDS’s components, too, are open source software.
JDS, a hardened enterprise Linux distro, contrasts dramatically to what we call “popular Linux.” The latter is exemplified by Fedora Core 2 (or now, 3), SuSE Linux Desktop (9.x), Slackware, Gentoo, Debian, and others, which have the very latest Linux kernel and the latest versions of open source applications. JDS, being built upon older, more stable components, has faced criticism from open source users who are accustomed to the latest Free Software components and are willing to live with the attendant instability and incompleteness of the application toolset. But such critics are consistently out of touch with enterprise software demands, often unable to see the necessity or the value proposition to large organizations of completeness and integration over currency.
It’s important also to note that JDS will be available by the end of 2004 to run on Solaris workstations and on the Sun Ray thin-client system, as well as Linux.
