I was wondering where things stood on official support for grub2 in
EFI environments. As far as I'm aware the status is:
initial patches were provided by "phcoder" about a year ago
these haven't been merged into the grub2 distribution
these haven't been merged with subsequent changes to OpenSolaris ZFS
or the grub 0.97 fork maintained by the Sun and the OpenSolaris
community
there is some work that may be in progress or pending for Caiman that
would include not just the grub2 updates but beadmin support and other
touch points in the installer
it's not clear yet whether the kernel still needs "fakebios" support
for bootstrapping in EFI environments, as there appeared to be some
issues here to remove legacy BIOS dependencies in the x86 code
the grub2 build toolchain hasn't been extended beyond Linux/GNU tools
and will require some adaptation to support native builds on OpenSolaris
I've trying to sort elements of this out for my own benefit and was
looking at merging phcoder's patches (http://lists.gnu.org/archive/html/grub-devel/2009-04/msg00512.html
) and the latest updates to the OpenSolaris grub-0.97 fork to
grub-1.97~beta4, which is on my understanding the last stable release
of grub2 (I may be mistaken, as there are later builds of 1.97, but
1.98 doesn't go anywhere with the build, even on Linux). I was hoping
I might make this more than a personal project and see if I could work
with someone with commit rights to get this code to a point where it
could be accepted into at least the OpenSolaris base. As I believe all
the code for grub-0.97 is supposed to be released under GPL (http://blogs.sun.com/darren/entry/zfs_under_gplv2_already_exists
), I was also hoping that the patches might be also be written with a
view to adding them to the GNU mainline or at least a recognised
branch in their bazaar repo, thus allowing other OS distros to provide
support for OpenSolaris install detection and boot in their build and
reducing requirements for chainloading. I've seen some mails
indicating that this requires an ARC review, which I assume means that
it's considered an architectural change and requires more extensive
review and approval, but I'm not clear on how that would impact my
ability to contribute.
Alternatively, I may be missing out on work already pending or
completed to resolve this, in which case I'm happy to test anything
that's considered suitable for community access.
Cheers,
Bayard
