Disable network configuration services during boot time

A better ideea than disabling the service is to remove the sleep time. To do this, open /etc/init/failsafe.conf with your favourite editor, and around line 25 you should see the following lines of code:

# Plymouth errors should not stop the script because we *must* reach
# the end of this script to avoid letting the system spin forever
# waiting on it to start.
$PLYMOUTH message –text=”Waiting for network configuration…” || :
sleep 40
$PLYMOUTH message –text=”Waiting up to 60 more seconds for network configuration…” || :
sleep 59
$PLYMOUTH message –text=”Booting system without full network configuration…” || :

To solve your problem, just comment the sleep times (add '#' in front of the text). It should look like this:

# Plymouth errors should not stop the script because we *must* reach
# the end of this script to avoid letting the system spin forever
# waiting on it to start.
$PLYMOUTH message –text=”Waiting for network configuration…” || :
#sleep 40
$PLYMOUTH message –text=”Waiting up to 60 more seconds for network configuration…” || :
#sleep 59
$PLYMOUTH message –text=”Booting system without full network configuration…” || :

In /etc/init/rc-sysinit.conf

replace:

start on (filesystem and static-network-up) or failsafe-boot

with:

start on (filesystem) or failsafe-boot
