I am not explicitly setting DEBIAN_FRONTEND and I have never set that myself. I did change menu.lst at one point (playing with splash and quiet) and do remember getting prompted by grub. I said to keep the currently installed version:
$ echo "get grub/update_grub_changeprompt_threeway" | debconf-communicate
0 keep_current
I thought this meant don't change things like defoptions, altoptions, etc and didn't think it would have anything to do with my AUTOMAGIC kernels.
I also now know why the strace didn't do anything-- I didn't realize update-grub was a shell script! I have attached update-grub modified with '#!/bin/bash -x' output.
