From 62b3c9bf77feda2ae595c5e811b3918d3bf990a4 Mon Sep 17 00:00:00 2001

Subject: [PATCH 216/216] Only attempt to scan different BLS directories on EFI
machines
Current BLS support attempted to scan for BLS directories, but this only
makes sense on EFI, where BLS fragments are in /loader/$vendor/entries.
For BIOS, only either the default /loader/entries path should be scanned
or the BLS directory defined in the blsdir GRUB 2 environment variable.
