Hi,

update-grub is now just a stub to grub-mkconfig which prints config by
default to stdout.
It's just now so designed and I doubt we make the effort to change this.
It wouldn't be easy because we call the scripts in /etc/grub.d/* which
prints to stdout their config.
For example just see /etc/grub.d/40_custom
If we would change this then any user having a custom script (and for
example memtest86/memtest86+) need to be changed too.
I don't think it's worth the effort but maybe someone can provide a
patch for this.
