12
13  <para>When logged in as user <systemitem class="username">root</systemitem>,
14  making a single mistake can damage or destroy a system. Therefore, we
15  recommend building the packages as an unprivileged user.
16  You could use your own user name, but to make it easier to set up a clean
17  work environment, create a new user called <systemitem
18  class="username">clfs</systemitem> as a member of a new group (also named
19  <systemitem class="groupname">clfs</systemitem>) and use this user during
20  the installation process. As <systemitem class="username">root</systemitem>,
21  issue the following commands to add the new user:</para>
22
23<screen><userinput>groupadd clfs
24useradd -s /bin/bash -g clfs -d /home/clfs clfs
25mkdir -pv /home/clfs
26chown -v clfs:clfs /home/clfs</userinput></screen>

56  <para>To log in as <systemitem class="username">clfs</systemitem> (as
57  opposed to switching to user <systemitem class="username">clfs</systemitem>
58  when logged in as <systemitem class="username">root</systemitem>, which
59  does not require the <systemitem class="username">clfs</systemitem> user
60  to have a password), give <systemitem class="username">clfs</systemitem>
61  a password:</para>
62
63<screen><userinput>passwd clfs</userinput></screen>
64
65  <para>Grant <systemitem class="username">clfs</systemitem> full access to
66  <filename class="directory">${CLFS}/cross-tools</filename> and
67  <filename class="directory">${CLFS}/tools</filename> by making <systemitem
68  class="username">clfs</systemitem> the directorys' owner:</para>
69
70<screen><userinput>chown -v clfs ${CLFS}/tools
71chown -v clfs ${CLFS}/cross-tools</userinput></screen>
72
73  <para>If a separate working directory was created as suggested,
74  give user <systemitem class="username">clfs</systemitem> ownership of this directory:</para>
75
76<screen><userinput>chown -v clfs ${CLFS}/sources</userinput></screen>
77
78  <para>Next, login as user <systemitem class="username">clfs</systemitem>.
79  This can be done via a virtual console, through a display manager, or
80  with the following substitute user command:</para>
81
82<screen><userinput>su - clfs</userinput></screen>
83
84  <para>The <quote><parameter>-</parameter></quote> instructs
85  <command>su</command> to start a login shell as opposed to a non-login
86  shell. The difference between these two types of shells can be found
87  in detail in <filename>bash(1)</filename> and <command>info
