I''m trying to help collect information about implementing raidz boot support. At the same time there is also the possibility that the work would overlap and take advantage of other grub 2 features allowing booting from drives larger than 1T. So if any zfs developers are kind enough to give more technical details.. While not so much detail this does give a nice high level overview.. http://blogs.sun.com/bonwick/entry/raid_z So the obvious question.. best approach to traversing the filesystem metadata? The other question that I am less worried about is would this violate any patents.. I mean.. Sun added the initial zfs support to grub and this is essentially extending that, but I''m not aware of any patent provisions on that code or some royalty free statement about ZFS related patents from Sun.. (Frankly.. I look at Sun as /similar/ to Cononical in that I assume they only sue to protect themselves and not go after any good intention foss project..) Thanks ./C ps.. I''m codestr0m in #ospkg on irc.freenode.net if anyone has any questions/comments/suggestions/wants to help

So this doesn''t apply.

So this doesn''t apply.Under GPLv2 you may only cntribute code where your patents apply if you grant royal free usage. BTW: this is why the FreeDB (CDDB) code is still free.
