I can create my own static kernel image with zfs and use it on my own though (and this is my preferred method of using it). You are also able to use proprietary kernel modules as well. Ever use the AFS (filesystem) on Linux? Here is a link as to what Linus has to think on the mater. http://linuxmafia.com/faq/Kernel/proprietary-kernel-modules.html The CDDL provides a patent grant and the conflict only affects distribution of linked binaries on the GPL end. Since the modules are from Solaris, they are not considered a derived work, so the derived work in the GPL is irrelevant. It is my interpretation that I can make and distribute a module, but that is not the question here. So, do you think the name for that zfs property would be accurate (rootcontext)? -- -- Matthew Thode
