12
13 <para>It is time to create some structure in the LFS file system. Create a
14 standard directory tree by issuing the following commands:</para>
15
16<screen><userinput>mkdir -pv /{bin,boot,etc/{opt,sysconfig},home,lib/firmware,mnt,opt}
17mkdir -pv /{media/{floppy,cdrom},sbin,srv,var}
18install -dv -m 0750 /root
19install -dv -m 1777 /tmp /var/tmp
20mkdir -pv /usr/{,local/}{bin,include,lib,sbin,src}
21mkdir -pv /usr/{,local/}share/{color,dict,doc,info,locale,man}
22mkdir -v /usr/{,local/}share/{misc,terminfo,zoneinfo}
23mkdir -v /usr/libexec
24mkdir -pv /usr/{,local/}share/man/man{1..8}
25
26case $(uname -m) in
27 x86_64) mkdir -v /lib64 ;;
28esac
29
30mkdir -v /var/{log,mail,spool}
31ln -sv /run /var/run
32ln -sv /run/lock /var/lock
33mkdir -pv /var/{opt,cache,lib/{color,misc,locate},local}</userinput></screen>
34
35 <para>Directories are, by default, created with permission mode 755, but
36 this is not desirable for all directories. In the commands above, two
37 changes are made&mdash;one to the home directory of user <systemitem
38 class="username">root</systemitem>, and another to the directories for
39 temporary files.</para>
40
41 <para>The first mode change ensures that not just anybody can enter
42 the <filename class="directory">/root</filename> directory&mdash;the
43 same as a normal user would do with his or her home directory. The
44 second mode change makes sure that any user can write to the
45 <filename class="directory">/tmp</filename> and <filename
46 class="directory">/var/tmp</filename> directories, but cannot remove
47 another user's files from them. The latter is prohibited by the so-called
48 <quote>sticky bit,</quote> the highest bit (1) in the 1777 bit mask.</para>

51 <title>FHS Compliance Note</title>
52
53 <para>The directory tree is based on the Filesystem Hierarchy Standard
54 (FHS) (available at <ulink
55 url="https://wiki.linuxfoundation.org/en/FHS"/>). The FHS also specifies
56 the optional existence of some directories such as <filename
57 class="directory">/usr/local/games</filename> and <filename
58 class="directory">/usr/share/games</filename>. We create only the
59 directories that are needed. However, feel free to create these
60 directories. </para>
