Not meant to berate anyone, but just like me sometimes I forget the newer images run Jessie, which default to using systemd as the systems init daemon. Anyway, with systemd there is no /etc/inittab, and serial or other things that were norally handled by inittab are instead written as startup services suppose . . . So for those of you who run the latest testing image . . . there is not inittab unfortunately.
