Linux: BOOTPROTO in /etc/sysconfig/network-scripts/*

Interface configuration (ifcfg) files control the software interfaces for individual network devices. As the system boots, it uses these files to determine what interfaces to bring up and how to configure them. These files are usually named ifcfg-name, where the suffix name refers to the name of the device that the configuration file controls. By convention, the ifcfg file's suffix is the same as the string given by the DEVICE directive in the configuration file itself. The BOOTPROTO setting is used to determine which protocol to use at boot time: - none: No boot-time protocol should be used - bootp: The bootp now pump protocol should be used - dhcp: The dhcp protocol should be used
