120 <systemitem class="groupname">nogroup</systemitem> group have been

128 <note>
129 <para>The classic uid and gid values are 65534 which is also -2 when
130 interpreted as a signed 16-bit number. These values impact other files
131 on some filesystems that do not have support for sparse files. The
132 <systemitem class="username">nobody</systemitem> and <systemitem
133 class="groupname">nogroup</systemitem> values are relatively arbitrary.
134 The impact on a server is nil if the <filename>exports</filename> file
135 is configured correctly. If it is misconfigured, an
136 <command>ls -l</command> or <command>ps</command> listing will show a
137 uid or gid number of 65534 instead of a name. The client uses <systemitem
