They will need to be looked at a bit more closely. Note to translators: I am very, very sorry. There was no *clean* way to merge this as separate commits. Trust me, I tried. The revision logs for the ISBN branch should provide some insight to what content has changed. I am more than happy to help out here. Sorry :( Approved by: doceng (implicit)

+ <title>Becoming Superuser</title>
+
+ <para>There are several ways to do things as the superuser. The
+ worst way is to log in as <username>root</username> directly.
+ Usually very little activity requires <username>root</username>
+ so logging off and logging in as <username>root</username>,
+ performing tasks, then logging off and on again as a normal user
+ is a waste of time.</para>
+
+ <para>A better way is to use &man.su.1; without providing a login
+ but using <literal>-</literal> to inherit the root environment.
+ Not providing a login will imply super user. For this to work
+ the login that must be in the <groupname>wheel</groupname> group.
+ An example of a typical software installation would involve the
+ administrator unpacking the software as a normal user and then
+ elevating their privileges for the build and installation of
+ the software.</para>
+
+ <example>
+ <title>Install a Program As The Superuser</title>
+
+ <screen>&prompt.user; <userinput>configure</userinput>
+&prompt.user; <userinput>make</userinput>
+&prompt.user; <userinput>su -</userinput>
+Password:
+&prompt.root; <userinput>make install</userinput>
+&prompt.root; <userinput>exit</userinput>
+&prompt.user;</screen>
+ </example>
+
+ <para>Note in this example the transition to
+ <username>root</username> is less painful than logging off
+ and back on twice.</para>
+
+ <para>Using &man.su.1; works well for single systems or small
+ networks with just one system administrator. For more complex
+ environments (or even for these simple environments)
+ <command>sudo</command> should be used. It is provided as a port,
+ <filename role="package">security/sudo</filename>. It allows for
+ things like activity logging, granting users the ability to only
+ run certain commands as the superuser, and several other
+ options.</para>
