Unfortunately, there are two errors with this: first, sshd must be called with the complete path (to guard against trojans), and init must be told to reload the configuration file after the change.

The following corrects both problems:

# sed -i -e "/^~~/ish:S:respawn:/usr/sbin/sshd -Do 'AllowUsers=root'" /etc/inittab
# telinit q
