        <p>For more information read
	<a href="https://crux.nu/Wiki/FakerootPorts">Fakeroot Ports</a>.
	Add a user that will be used by ports tools, this example pkgmk;</p>

        <pre>
        # useradd -r -U -d /usr/ports -s /bin/false pkgmk
        </pre>

        <p>You can add your self to group pkgmk. Check if members of this
        group are under <a href="linux.html#sysctl">tpe</a> protection.</p>

        <pre>
        # usermod -a -G pkgmk username

        average of 3GB is recommended for core while firefox need at least 30G.
	Discover id of pkgmk user;</p>

        <p>Edit fstab, change uid to id of pkgmk, this example 102;</p>

        to take advantage of your specific hardware. Packages build with
        native flag will not run on different hardware. This is the best choice
        if you want gcc to find the best settings based on your hardware.</p>

        <p>Edit /etc/pkgmk.conf, remove pipe from compiler flags and let the system
        get from nproc how many cpu's it can use for compiling;</p>
