Which location would that be? I mean, it will write to locations its not
supposed to write to.

And running grub2-mkconfig already takes ages today, even with all knobs being
off. So I think an unconditional run of 'grub --batch < /etc/grub.conf' or
similar will cause no complain.

The response to such user complains there should be some hard profiling data,
where the time is actually spent. Do such data exist already?
