I'm not sure what version of bash you used on Ubuntu 12.10, but I tested
versions of bash back to bash-3.0, and they all behave as the documentation
states:
ignoreeof
The effect is as if the shell command
``IGNOREEOF=10'' had been executed (see Shell
Variables above).
Whether you execute the two commands above (which are more or less
equivalent) from the command line or in a startup file, the effect is the
same: the shell exits after you type ^D eleven times.
