The bootloader plugin needs patched BLS entries with the TuneD variables. It seems variables in the BLS entries is grub extension which is not described in the BLS specification. It can cause boot problems with e.g. systemd-boot, thus add variables to BLS entries only if the BLS entries were generated by grub.
