Multiple refind.conf files breaks the theme
I have two refind.conf files on my system:
/boot/efi/EFI/refind/refind.conf
/boot/efi/EFI/Boot/refind.conf
That makes the script fail, because it's only expected to find one or zero.
It would be nice to either apply the changes to all files individually, or be able to choose to which one(s) to apply.
