Any patent Sun has on things released under GPLv2 is open for use. I don't know anything about CDDL rules, but if you don't look at it, you won't be legally contaminated. I have not looked at the ZFS grub code, but a general warning based on my experience with other filesystem bootstrap code is that it may be very limited and not be able to deal with all structures on a ZFS filesystem... you won't know until you hit one of them and fail. jim -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
