Created attachment 337862 [details, diff] Feature flag support patch for sys-boot/grub:2 The latest version of ZFSOnLinux adds support for feature flags, which is incompatible with sys-boot/grub:2. There are warnings about compatibility in the ZFS ebuilds. However, one user has already reported to me that he has a non-bootable system, so I consider adding feature flags to be a high priority. I started a port of feature flag support from Illumos to GRUB2, but maxximino from #zfsonlinux on freenode informed me that he has already done the work. His work was against GRUB2 HEAD, but it applies perfectly to our current GRUB2 package. I have attached a monolithic patch containing his work, plus a tiny fix so that the result builds properly. I have tested this on my own system and I can confirm that it works properly. As per an agreement with floppym in IRC, I am committing sys-boot/grub-2.00-r2 masked for his inspection. I am opening this bug to serve as a reference in the ebuild.
