These early -images will be loaded in the order declared, and all will be loaded -before the initrd image. - -While many classes of data can be provided by early images, the -immediate use case would be for distributions to provide CPU -microcode to mitigate the Meltdown and Spectre vulnerabilities. - -There are two environment variables provided for declaring the early -images. - -* GRUB_EARLY_INITRD_LINUX_STOCK is for the distribution declare - images that are provided by the distribution or installed packages. - If undeclared, this will default to a set of common microcode image - names. - -* GRUB_EARLY_INITRD_LINUX_CUSTOM is for user created images. User - images will be loaded after the stock images. - -These separate configurations allow the distribution and user to -declare different image sets without clobbering each other. - -This also makes a minor update to ensure that UUID partition labels -stay disabled when no initrd image is found, even if early images are -present. - -This is a continuation of a previous patch published by Christian -Hesse in 2016: -http://lists.gnu.org/archive/html/grub-devel/2016-02/msg00025.html - -Down stream Gentoo bug: -https://bugs.gentoo.org/645088 - -Signed-off-by: Robin H.
