TuneD sets variables in grubenv - arguably risky (may run out of very limited space), and unnecessary?

[mikebeaton]

After intialising a TuneD profile which uses [bootloader] it sets up the variables tuned_params and tuned_initrd in both grub.cfg and grubenv.

It seems that there is no need to set these variables in both places, and quite a strong argument against setting them in grubenv - namely, space there is extremely limited, and the values of these variables could validly be very long.
