I misuderstood.  The blank is while kbl-kexec loads, yes.

Ok.  That makes sense.  I thought I saw the linuxbios part of that
attempts to detect when you have make a change to the config file and
try to rebuild.  I extrapolated that the other targets would do the
same.

So is the following is true?

When do a get pull you either need to clean and rebuild the entire
tree or you have to look at the diffstat and make pkg-clean on every
package that has changed in the tree.

If so then we probally need to document it somewhere and have a reminder.

I got the numbers because the previous loader we had before bootmenu
took numbers to select the boot option and  the linuxrc script checks
for return codes  0 1 2 3  or  -1.  I made a bad assumption that
bootmenu would do the same.   When presing the number keys didn't work
I started looking as to why.
I saw the ESC in the code and knowing that the keypad does an escape I
jumped to 123 on the keypad.  Since it just "worked" I didn't really
look at the code hard enough to see I was wrong.  My bad that I didn't
verify my scan codes.  Thanks for the correction.

At 3:30am, I admit,  my clarity was suffering.  I probably should have
quit before then.  So cool.  None of this is an issue then.
