+ <listitem>
+ <para>
+ This parameter specifies which values in the <emphasis
+ remap='I'>gecos</emphasis> field of the
+ <filename>/etc/passwd</filename> file may be changed by regular
+ users using the <command>chfn</command> program. It can be any
+ combination of letters <replaceable>f</replaceable>,
+ <replaceable>r</replaceable>, <replaceable>w</replaceable>,
+ <replaceable>h</replaceable>, for Full name, Room number, Work
+ phone, and Home phone, respectively. For backward compatibility,
+ <replaceable>yes</replaceable> is equivalent to
+ <replaceable>rwh</replaceable> and <replaceable>no</replaceable> is
+ equivalent to <replaceable>frwh</replaceable>. If not specified,
+ only the superuser can make any changes. The most restrictive
+ setting is better achieved by not installing <command>chfn</command>
+ SUID.
