31  but this is not desirable for all directories. In the commands above,
32  two changes are made&mdash;one to the home directory of user
33  <systemitem class="username">root</systemitem>, and another to the
34  directories for temporary files.</para>
35
36  <para os="c">The first mode change ensures that not just anybody can enter
37  the <filename class="directory">${LFS}/root</filename> directory&mdash;the
38  same as a normal user would do with his or her home directory. The
39  second mode change makes sure that any user can write to the
40  <filename class="directory">${LFS}/tmp</filename> and
41  <filename class="directory">${LFS}/var/tmp</filename> directories, but
42  cannot remove another user's files from them. The latter is prohibited
43  by the so-called <quote>sticky bit,</quote> the highest bit (1) in the
44  1777 bit mask.</para>

49    <para>The directory tree is based on the Filesystem Hierarchy Standard
50    (FHS) (available at <ulink url="http://www.pathname.com/fhs/"/>). In
51    addition to the tree created above, this standard stipulates the
52    existence of <filename class="directory">/usr/local/games</filename>
53    and <filename class="directory">/usr/share/games</filename>. The FHS
54    is not precise as to the structure of the <filename
55    class="directory">/usr/local/share</filename> subdirectory, so we
56    create only the directories that are needed. However, feel free to
57    create these directories if you prefer to conform more strictly to
58    the FHS.</para>
