"Don't expect to see key features of OpenSolaris showing up in the Linux kernel," said a top Linux maintainer. At his LinuxWorld opening keynote, Andrew Morton made it very clear that the appointment of former OSDL CTO and Debian co-founder Ian Murdock to Sun's OS platforms organization will not translate into a merging between the open source version of Solaris Unix with Linux. He didn't mince words. "It's a great shame that OpenSolaris still exists. They should have killed it," said Morton, addressing one attendee's question about the possibility of Solaris' most notable features being integrated into the kernel. "It's a disappointment and a mistake by Sun." Morton said none of those features - Zones, ZFS, DTrace - will end up in the Linux kernel because Sun refuses to adopt the GPL.
