This is a dirty hack that tidies things up a bit, depending on how your cli system is set up. I was too lazy to hand configure my wireless card, so I used wicd-curses. However, this doesn’t kick in until I am booted up. So I get the waiting for network delays of @ 1.5 minutes on the plymouth screen. To remove these, I had to edit a file:
sudo nano /etc/init/failsafe.conf
and then comment out the two sleep commands related to these messages, and comment out the resultant message about booting with no network. The segment in question should end up looking 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..." || :
Just remember you have done this if you decide to change your networking approach!
