I have remastered a Ubuntu 13.04 Live-CD for software presentations. During boot, it tries to find a network connection for several minutes (but fails in the end). Maybe it does not detect my network card properly (MacBook Pro). For the live system I don't need an internet connection. Only access to localhost is important.
How do I prevent the system from configuring the network/internet connection while still preserving access to localhost?
If I can not turn this off, is it possible to reduce the timeout for this configuration process?
EDIT: I forgot to say that I used a minimal Ubuntu 13.04 with command line only. Hence, no GUI components are responsible for the delay.
EDIT 2: The /etc/network/interfaces
of the Live-DVD before remastering is
# interfaces(5) file used by ifup(8) and ifdown(8)
auto lo
