Subject: [PATCH] fix(dracut.sh): handle imagebase for uefi
|
||
|
|
|
||
|
|
* UEFI creation didn't handle the ImageBase data for the PE file
|
||
|
|
generation. Create an UKI thanks a stub file with a non zero BaseImage
|
||
|
|
logs some warning ans generate a bad file offset management. The efi
|
||
|
|
becomes unloadable.
|
||
|
|
* This commit parse the PE file header, get the data and apply the
|
||
|
|
ImageBase on the objcopy command.
|
||
|
|
|
||
|
|
Fixes dracutdevs#2284
