The grub-editenv create command will wrongly overwrite /boot/grub2/grubenv with a regular file if grubenv is a symbolic link. But instead, it should create a new file in the path the symlink points to. This lets /boot/grub2/grubenv be a symlink to /boot/efi/EFI/fedora/grubenv even when they're different mount points, which allows grub2-editenv to be the same across platforms (i.e. UEFI vs BIOS). For example, in Fedora the GRUB EFI builds have prefix set to /EFI/fedora (on the EFI System Partition), but for BIOS machine it'll be /boot/grub2 (which may or may not be its own mountpoint). With this patch, on EFI machines we can make /boot/grub2/grubenv a symlink to /boot/efi/EFI/fedora/grubenv, and the same copy of grub-set-default will work on both kinds of systems. Windows doesn't implement a readlink primitive, so the current behaviour is maintained for this operating system.

This is GRUB 2, the second version of the GRand Unified Bootloader. GRUB 2 is rewritten from scratch to make GNU GRUB cleaner, safer, more robust, more powerful, and more portable. See the file NEWS for a description of recent changes to GRUB 2. See the file INSTALL for instructions on how to build and install the GRUB 2 data and program files. Please visit the official web page of GRUB 2, for more information. The URL is <http://www.gnu.org/software/grub/grub.html>. More extensive documentation is available in the Info manual, accessible using 'info grub' after building and installing GRUB 2. There are a number of important user-visible differences from the first version of GRUB, now known as GRUB Legacy. For a summary, please see: info grub Introduction 'Changes from GRUB Legacy'
