Where to find the inittab in Ubuntu Linux
In most variants of GNU/Linux the init daemon and its configuration file /etc/inittab are used to define things like runlevels and consoles. In an effort to improve boot time, system performance and ease scripted configuration, ubuntu has implemented upstart, an event-based replacement for the traditional init daemon. This is good for the most part, but in different versions ubuntu upstart is configured in different locations which can be quite confusing.
Aside from the change in location, the items that traditionaly would be represented by a line in /etc/inittab have been split up into individual files. Despite this difference, the syntax used within the individual files is very familiar.
With all that said, here’s where “inittab” lives on different version of ubuntu.
