<term><option>CHFN_RESTRICT</option> (string)</term>
<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.
