[PATCH v1 1/2] efi_loader: improve device path matching for partition lookup

[Balaji Selvanathan]

Hi Ilias,

   Sorry for the late reply.
   If i point to esp, then it should work.
   But in the boot option generation, they are skipping if its a partition:
             i.e., in lib/efi_loader/efi_bootmgr.c: 
efi_bootmgr_enumerate_boot_options(), in this code (line 838):
                 if (blkio->media->logical_partition)
                         continue;
   It seems that, by default, the boot option generation logic is not 
designed to include partition as a boot option; Not sure if this is 
intentional. If its not, then should we correct this logic? Your inputs 
are appreciated.
