From 24865a88781aef2a6a54433b5b383219108f54fa Mon Sep 17 00:00:00 2001 From: Fedora Ninjas Date: Wed, 19 Feb 2014 15:58:43 -0500 Subject: [PATCH] use fw_path prefix when fallback searching for grub config When PXE booting via UEFI firmware, grub was searching for grub.cfg in the fw_path directory where the grub application was found. If that didn't exist, a fallback search would look for config file names based on MAC and IP address. However, the search would look in the prefix directory which may not be the same fw_path. This patch changes that behavior to use the fw_path directory for the fallback search. Only if fw_path is NULL will the prefix directory be searched.
