I found more answers in /etc/inittab in the installer BusyBox
environment and saved a copy of it to show here ...

$ grep tty busybox-etc-inittab
tty2::askfirst:-/bin/sh
tty3::askfirst:-/bin/sh
tty4::respawn:/usr/bin/tail -f /var/log/syslog
tty0::respawn:/sbin/debian-installer

And if I understand correctly, tty0 is "the current tty" which
for some reason must get activated as /dev/pts/0 rather
than /dev/tty1.
