The latest upstream gummiboot version contains a handy installer/updater tool [1] which does not seem be part of the package. Please build and add it to the package (maybe the update command could even be part of post_upgrade?).

As a btw, this makes me wonder why the x86_64 and i686 builds of gummiboot are not in separate packages, any specific reason for this?

This task depends upon

The reason for not having them seperated is because it depends on the UEFI of your vendor if it is i686 or x86_64.

Due to the limitation of devtools in not allowing mixed arch packages from same split PKGBUILD, I have created a separate PKGBUILD for gummiboot setup without touching the existing gummiboot-efi PKGBUILD. See the attached gummiboot-efi-setup src.tar.gz file.

EDIT: You can also add gummiboot-efi-setup as optdepends to gummiboot-efi pkg.

EDIT 2: One more thing to note is that gummiboot-setup requires /sys/firmware/efi/efivars support which is present only in kernels >=3.8, so it won't work with 3.7 and LTS kernels.

I thought efivars is in the kernel since 2.6.32.

@tpowa: What you mean is the recently deprecated efi variables interface /sys/firmware/efi/vars which was designed for EFI 1.x spec actually and has some limitations (regarding secure boot etc.) which was fixed in an upgraded efivars interface /sys/firmware/efi/efivars which is actually the recommended interface now. Since the new interface is incompatible with the old one, the sysfs path for this one is different the old one. See for more info.

efibootmgr has not yet been updated upstream to support this new interface. This gummiboot-setup essentially duplicates efibootmgr functionality and the whole file copying/syncing work, but hardcoded for gummiboot alone.

@tpowa: thanks for the clarification, makes sense.

@the.ridikulus.rat: thanks, the PKGBUILD works fine and after some playing around, the install/remove/update procedures seem to work as expected on my Samsung 900x4d. On kernel 3.7 it will simply complain that efivars is not mounted, on kernel 3.8 efivars is mounted automatically (I guess it's mounted by systemd).
