okay I think I figured that one out.... it is update-grub.

For your edification I asked at one point how to get  the os to load a
specific kernel w/o pressing esc each time and selecting it out of the
list. I never got an answer.  Anyways this is how you do it:
get grub to look like this:

GRUB_SAVEDEFAULT=true
GRUB_DEFAULT=saved
then run:

sudo update-grub
