Subject: [PATCH] use fw_path prefix when fallback searching for grub config
|
|
|
d9d99f |
|
|
|
d9d99f |
When PXE booting via UEFI firmware, grub was searching for grub.cfg
|
|
|
d9d99f |
in the fw_path directory where the grub application was found. If
|
|
|
d9d99f |
that didn't exist, a fallback search would look for config file names
|
|
|
d9d99f |
based on MAC and IP address. However, the search would look in the
|
|
|
d9d99f |
prefix directory which may not be the same fw_path. This patch
|
|
|
d9d99f |
changes that behavior to use the fw_path directory for the fallback
|
|
|
d9d99f |
search. Only if fw_path is NULL will the prefix directory be searched.
