This feature looks very useful, but I have not found a shred of
documentation for it. The one aspect I can think of that is
not completely obvious is the order that the grub default files are read.
I did find from reading /usr/sbin/grub-mkconfig
that all of the /etc/default/grub.d files are read in order,
AFTER the /etc/default/grub file.
I hope that this point is noted when this feature does appear in
the Grub2 docs.
