[fb40919]13 <para os="a">It is time to create some structure in the CLFS file system. Create a
[3f8be484]14 standard directory tree by issuing the following commands:</para>

[fd6bb04]16<screen os="b"><userinput>mkdir -pv ${CLFS}/{bin,boot,dev,{etc/,}opt,home,lib,mnt}
[6b2fbfc]17mkdir -pv ${CLFS}/{proc,media/{floppy,cdrom},run/{,shm},sbin,srv,sys}

[d012cdb5]30 <para os="c">Directories are, by default, created with permission mode 755,
[3f8be484]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
[d012cdb5]36 <para os="d">The first mode change ensures that not just anybody can enter
[91ad4a4]37 the <filename class="directory">/root</filename> directory&mdash;the
[3f8be484]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
[91ad4a4]40 <filename class="directory">/tmp</filename> and
41 <filename class="directory">/var/tmp</filename> directories, but
[3f8be484]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>

[3f8be484]47 <title>FHS Compliance Note</title>
48
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>
