From: Xiangyu Chen <[email protected]>
Grub would report an error message in boot stage as below:
"error: no such device: ((hd0,gpt1)/EFI/BOOT)/EFI/BOOT/grub.cfg"
Consequently, the root variable is not set, and the intended protection
against cross-device configuration loading (the purpose of the original 2014
commit)
is lost.
The most robust fix is to use the --hint parameter.
This separates the search target from the device hint, avoiding
fragile string concatenation and supporting both prefixed and
non-prefixed $cmdpath formats.
Fixes: 5ce73b6055ac ("grub: add cmdpath to grub configuration file")
