+ <para>The server will <command moreinfo="none">chroot()</command> (i.e.
+ Change its root directory) to this directory on startup. This is
+ not strictly necessary for secure operation. Even without it the
+ server will deny access to files not in one of the service entries.
+ It may also check for, and deny access to, soft links to other
+ parts of the filesystem, or attempts to use &quot;..&quot; in file names
+ to access other directories (depending on the setting of the <link linkend="WIDELINKS">
+ <parameter moreinfo="none">wide links</parameter></link>
+ parameter).
+ </para>
+
+ <para>Adding a <parameter moreinfo="none">root directory</parameter> entry other
+ than &quot;/&quot; adds an extra level of security, but at a price. It
+ absolutely ensures that no access is given to files not in the
+ sub-tree specified in the <parameter moreinfo="none">root directory</parameter>
+ option, <emphasis>including</emphasis> some files needed for
+ complete operation of the server. To maintain full operability
+ of the server you will need to mirror some system files
+ into the <parameter moreinfo="none">root directory</parameter> tree. In particular
+ you will need to mirror <filename moreinfo="none">/etc/passwd</filename> (or a
+ subset of it), and any binaries or configuration files needed for
+ printing (if required). The set of files that must be mirrored is
+ operating system dependent.</para>
