Bug#3227: login refuses, and then allows, root login on tty?

Plain standard:

edd@miles:~> dpkg -l getty sysvinit | grep ^ii
ii  getty           1.0-4          agetty, an alternative Linux getty.
ii  sysvinit        2.61-2         System-V like init.

edd@miles:~> grep tty /etc/inittab
# /sbin/getty invocations for the runlevels.
# characters of the device (after "tty").
1:2345:respawn:/sbin/getty 9600 tty1
2:23:respawn:/sbin/getty 9600 tty2
# edd 12.09.95 commented out 4 of the 6 getty's
#3:23:respawn:/sbin/getty 9600 tty3
#4:23:respawn:/sbin/getty 9600 tty4
#5:23:respawn:/sbin/getty 9600 tty5
#6:23:respawn:/sbin/getty 9600 tty6
