<note>
|

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

<command>rpc.statd</command>.</para>
