115 created. You can add them by running the following commands as the

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