The argument should be an architecture identifier, using the architecture vocabulary defined by the EFI specification (i.e. `IA32`, `x64`, `IA64`, `ARM`, `AA64`, …). If specified and this does not match (case insensitively) the local system architecture this entry should be hidden. Each configuration drop-in snippet must include at least a `linux` or an `efi` key and is otherwise not valid. Here's an example for a complete drop-in file: # /boot/loader/entries/6a9857a393724b7a981ebb5b8495b9ea-3.8.0-2.fc19.x86_64.conf - title Fedora 19 (Rawhide) - version 3.8.0-2.fc19.x86_64 - machine-id 6a9857a393724b7a981ebb5b8495b9ea - options root=UUID=6d3376e4-fc93-4509-95ec-a21d68011da2 - linux /6a9857a393724b7a981ebb5b8495b9ea/3.8.0-2.fc19.x86_64/linux - initrd /6a9857a393724b7a981ebb5b8495b9ea/3.8.0-2.fc19.x86_64/initrd + title Fedora 19 (Rawhide) + version 3.8.0-2.fc19.x86_64 + machine-id 6a9857a393724b7a981ebb5b8495b9ea + options root=UUID=6d3376e4-fc93-4509-95ec-a21d68011da2 + architecture x64 + linux /6a9857a393724b7a981ebb5b8495b9ea/3.8.0-2.fc19.x86_64/linux + initrd /6a9857a393724b7a981ebb5b8495b9ea/3.8.0-2.fc19.x86_64/initrd On EFI systems all Linux kernel images should be EFI images. In order to increase compatibility with EFI systems it is highly recommended only to install EFI kernel images, even on non-EFI systems, if that's applicable and supported on the specific architecture. |
