ifup requires an existing interface, because it does not initialize the hardware. The
initialization of the hardware is handled by the command hwup (executed by hotplug
or coldplug). When a device is initialized, ifup is automatically executed for the
new interface via hotplug and the interface is set up if the start mode is onboot,
hotplug, or auto and the network service was started. Formerly, the command
ifup interfacename triggered the hardware initialization. Now the procedure has
been reversed. First, a hardware component is initialized then all other actions follow.
In this way, a varying number of devices can always be configured in the best way
possible with an existing set of configurations.

distinguished by hardware and interface.

Function
The hw* scripts are executed by the hot-
plug subsystem to initialize a device, un-
do the initialization, or query the status
of a device. More information is available
in the manual page of hwup.
getcfg can be used to query the inter-
face name associated with a configuration
name or a hardware description. More
information is available in the manual
page of getcfg.
The if* scripts start existing network
interfaces or return the status of the
specified interface. More information is
available in the manual page of ifup.
