Hi all, I (skodabenz) and Ronald Van Haren (pressh) have put together a split PKGBUILD for grub2 including UEFI support (apart from standard BIOS firmware). The first PKGBUILD (all links at the end of this post) builds grub2-common which contains the utilities common for all the platforms/firmware, grub2-bios containing grub2 bios firmware specific modules and grub2-efi-i386 containing grub2 i386 (32-bit) UEFI firmware specific modules. The second PKGBUILD builds grub2-efi-x86_64 containing grub2 x86_64 (64-bit) UEFI firmware specific modules. This is in a separate PKGBUILD as grub2-efi-x86_64 requires an x86_64 build system to compile. The firmware specific packages are dependent on the firmware but independent of linux kernel arch. Therefore they are built as any. If the present problem in the website regarding mixing arch and any packages in a single PKGBUILD is resolved, the PKGBUILDs will be used unmodified. The current grub2 1.98 package will be replaced by grub2-common and grub2-bios 1.99~rc1 . The packages also include modules from grub-extras project (part of upstream but maintained in a separate repo due to legal issues) like lua parser, gPXE modules etc. BTRFS support exists in grub2's experimental bzr branch but the 1.99~rc1 released tarball ( release info at http://lists.gnu.org/archive/html/grub-devel/2011-01/msg00082.html ) does not include btrfs support. However ZFS support is included. For a full Change Log for 1.99 release please go to http://bazaar.launchpad.net/~vcs-imports/grub/grub2-bzr/view/3072/NEWS . For those who are using the skodabenz-arch-grub2 repo, please remove it from pacman.conf (repo will not be maintained) and update your grub2 packages with the below ones (pkgver and pkgrel not updated). As usual these packages conflict with both the old grub (grub-legacy) and grub2 1.98 package. Comments are welcome. Regards. Keshav PS: Due to text folding the hyperlinks may not work. In that case copy-paste the links in your browser to download the packages.
