Is this the command you ran? If so, it would not have saved the change. You
either need to redirect the output to your grub.cfg file or run it with the -o
option like this:

# grub-mkconfig -o /boot/grub/grub.cfg

Currently I don’t have a Debian distro installed on SPARC. I think I need to
spend some time and set one up. So I'm assuming that is where your grub.cfg
should be saved.

I also see some things below that are not in my code that probably got changed
when grub was packaged up.

For example there is no need for colors

And I don’t think this should be here.
