File provide-option-in-config-to-enable-.patch of Package grub2
From: Michael Chang <mchang@suse.com> Date: Mon, 26 Nov 2012 15:38:54 +0800 Subject: [PATCH] provide option in config to enable linuxefi References: fate#314485 Patch-Mainline: no As linuxefi module requires kernel 3.6 or later which supports EFI handover protocol, it may not be able to load kernels without that supports in place. In case that things would break, and the linuxefi is really too young to take over the position of "linux" kernel loader module, we introduce a option GRUB_USE_LINUXEFI in the config and only explicit set it to true will enable it. Example usage is GRUB_USE_LINUXEFI=true grub2-mkconfig -o /boot/efi/EFI/opensuse/grub.cfg This will output a grub.cfg which uses linuxefi in replace of linux and enable verification of kernel signature if in secureboot enabled and has shim exported protocols available. --- util/grub-mkconfig.in | 3 ++- util/grub.d/10_linux.in | 4 ++-- 2 files changed, 4 insertions(+), 3 deletions(-) diff --git a/util/grub-mkconfig.in b/util/grub-mkconfig.in index 2d67864e0..63ec801b6 100644 --- a/util/grub-mkconfig.in +++ b/util/grub-mkconfig.in @@ -281,7 +281,8 @@ export GRUB_DEFAULT \ GRUB_BADRAM \ GRUB_OS_PROBER_SKIP_LIST \ GRUB_DISABLE_SUBMENU \ - GRUB_CMDLINE_LINUX_RECOVERY + GRUB_CMDLINE_LINUX_RECOVERY \ + GRUB_USE_LINUXEFI if test "x${grub_cfg}" != "x"; then rm -f "${grub_cfg}.new" diff --git a/util/grub.d/10_linux.in b/util/grub.d/10_linux.in index ba65e7659..58eb60593 100644 --- a/util/grub.d/10_linux.in +++ b/util/grub.d/10_linux.in @@ -145,7 +145,7 @@ linux_entry () printf '%s\n' "${prepare_boot_cache}" | sed "s/^/$submenu_indentation/" fi message="$(gettext_printf "Loading Linux %s ..." ${version})" - if [ -d /sys/firmware/efi ]; then + if [ -d /sys/firmware/efi ] && [ "x${GRUB_USE_LINUXEFI}" = "xtrue" ]; then sed "s/^/$submenu_indentation/" << EOF echo '$(echo "$message" | grub_quote)' linuxefi ${rel_dirname}/${basename} ${root_device} ${args} @@ -163,7 +163,7 @@ EOF for i in ${initrd}; do initrd_path="${initrd_path} ${rel_dirname}/${i}" done - if [ -d /sys/firmware/efi ]; then + if [ -d /sys/firmware/efi ] && [ "x${GRUB_USE_LINUXEFI}" = "xtrue" ]; then sed "s/^/$submenu_indentation/" << EOF echo '$(echo "$message" | grub_quote)' initrdefi $(echo $initrd_path)
