Ted Ts'o, one of the earliest Linux developers, points out some serious flaws in OpenSolaris
I was recently checking to see what, if any follow-up there had been from Sun’s ham-handed handling of the Open Solaris Trademark, and I ran across this very interesting comment from John Plocher’s Candidate Statement for the Open Solaris Governing Board:
“I also think there was a misunderstanding about what Sun desired when it launched the community (in part) to encourage developers to adopt and use Solaris. My take is that, while there *is* value in getting more kernel, driver and utility developers contributing to and porting the (open) Solaris operating system, there is significantly *more* value in having a whole undivided ecosystem based on a compatible set of distributions, where application developers, university students, custom distro builders and users are all able to take advantage of each other’s work.
Put these two things together, and you can see Sun’s predicament. Sun *wanted* a community that empowered application developers, but *got* a community aimed squarely at kernel hackers. Whether you see this as the “kernel.org -vs- Ubuntu” fight, or the “fully open -vs- MySQL model” argument, in my opinion, it all is simply a reflection of the above mismatched expectations.”
