Comment 1 for bug 67415

We migrate changes made to /etc/inittab on upgrade from dapper, from your bug report I assume that you have made these changes since installing edgy rather than before you upgraded?

upstart is not intended to actually parse the /etc/inittab file -- it's too free-form, and not really possible to do reliably. Modification of this by users is sufficiently rare, and those users sufficiently technically advanced, that we felt it would be better to document how to make these changes with upstart than try and honour them.

/usr/share/doc/upstart/README.Debian.gz contains the appropriate docs:

How do I change which runlevels gettys are run in?
--------------------------------------------------

In /etc/event.d there is a file named ttyN for each getty that will be
started, where N is numbered 1 to 6. Edit these files, there are a
series of lines of either "start on runlevel-N" or
"stop on runlevel-N".

Change "stop" to "start" or "start" to "stop" to match your taste.

This will not take immediate effect, however you can run "stop ttyN"
to stop one that is running or "start ttyN" to start one that isn't.
