Hmm, so this doesn't work for me.

./enter_chroot.sh -- sh -c 'echo $SUDO_USER' reports root, whereas
./enter_chroot.sh -- sh -c 'echo $USER' reports davidjames.

Here's the output I get for cros_overlay_list with your patch:

$ ./bin/cros_overlay_list --board tegra2 --variant seaboard
ERROR  : There is no variant overlay called 'seaboard'
