|

79 |
|

80 | <para>For meaningful results, the tests need to be carried out on a file

81 | system that supports extended attributes. It is also required that

82 | <application>Coreutils</application> is re-installed after

83 | <application>acl</application> is installed so that the extra acl bit

99 | <para>There are three sets of tests that come with this package. The local

102 | class="username">bin</systemitem> and <systemitem
|
---|
103 | class="username">daemon</systemitem> must be created or modified to have a
|
---|
104 | proper shell and home directory and the group <systemitem
|
---|
105 | class="groupname">daemon</systemitem> must be a member of the <systemitem
|
---|
106 | class="groupname">bin</systemitem> group. The kernel must also be
|
---|
107 | configured with the appropriate ACL options (there are nine different
|
---|
108 | options).</para>
|
---|
109 |
|

110 | <para>To run the standard tests run <command>make tests </command>. As
