EFI_MOUNTPOINT is conventionally /boot/efi or /boot/EFI or something
|
||||
like that, and (on my machine) has directories within that called
|
||||
{Boot, nixos, gummiboot}.
|
||||
|
||||
This patch does two things:
|
||||
|
||||
1) Xen apparently wants to put files in
|
||||
$(EFI_MOUNTPOINT)/efi/$(EFI_VENDOR) - we remove the duplicate 'efi' name
|
||||
because I can't see why we have it
|
||||
|
||||
2) Ensures the said directory exists
