It is common for a laptop user to use DHCP most of the time; however, they may also need to periodially connect to network where a static network configuration is required. This is a situation where a Funtoo Linux machine will require '''multiple''' network configurations. Funtoo Linux supports this.

The recommended approach for doing this is to use multiple, stacked runlevels. To do this, you will need to create two new runlevels which are children of the <tt>default</tt> runlevel. This can be done like this:

<pre># install -d /etc/runlevels/static
# install -d /etc/runlevels/dynamic</pre>
Two new runlevels, <tt>static</tt> and <tt>dynamic</tt>, have now been created. Now, we will make these runlevels children of the <tt>default</tt> runlevel using the following commands:

<pre># rc-update --stack add default static
# rc-update --stack add default dynamic</pre>
Now, the runlevels <tt>static</tt> and <tt>dynamic</tt> will consist of anything in <tt>default</tt> '''plus''' any additional scripts you add to each new runlevel.

To complete our multiple network configuration, we would now do something like this:

<pre># rc-update add netif.eth0 static
# rc-update add dhcpcd dynamic</pre>
To switch to or between each runlevel, we would type:

<pre># rc static</pre>
Or:

<pre># rc dynamic</pre>
If we wanted to boot into <tt>dynamic</tt> by default, this could be done by editing <tt>/etc/inittab</tt> and modifying this line:

<pre>l3:3:wait:/sbin/rc default</pre>
To read as follows:

<pre>l3:3:wait:/sbin/rc dynamic</pre>
