Thank you very much, based on this, I have solved most of the problem. I had to delete the password on the primary account, and delete a secondary account, so that it would not require a login or choosing an account, but it works very well.
The only loose end remaining is due to the fact that I'm powering down by putting the computer to sleep (it seems prudent to shutdown more gracefully that a hard shutdown), the boot options window appears on power up, delaying everything for ~ 30 seconds, which it would be nice to eliminate, but I doubt that is possible. In any case, I consider the problem solved.
