... but it looks like you still have some GPL-3 gremlins lurking. this must be sorted out before we can consider the code for merging. i suspect simply changing "version 3" to "version 2" isn't the right answer, otherwise i wonder where you copied this code from such that i has "version 3" in the first place. -mike
The code submitted by Sun to GRUB is version 2, and you can see that in the first GRUB version with ZFS (0.97 - I posted the url earlier).
However, GRUB opted to go higher ("or at your option any later version") sometime before the GRUB 2 release. I took the latest version available or the sources at the time of porting.
However, there is only one functional source change between the versions, and that is adding ashift support, which was supplied as a patch.
That "ZFS" and "license" produces a knee-jerk reaction is a little tedious. It is not the problem everyone thinks, and I invite you to run ZFS on Linux native. http://zfsonlinux.org/
