Being a wifi only user at home, it bugs me to see DHCP lookup slowing down my laptop’s boot time. I don’t use LAN (by decision) and it doesn’t make sense to have that DHCP stuff on boot time. I ask around and get a good answer from the Slackware forum.
My machine is configured to use DHCP to assign IP address automatically. However, I used NetworkManager to manage my wifi connection. According to the people at Slackware forum, all I have to do is disable /etc/rc.d/rc.inet1.
chmod -x /etc/rc.d/rc.inet1
That’s it. Few seconds (4-5 seconds) faster boot time for my laptop.
