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">lfs</systemitem> as a member of a new group (also named
19  <systemitem class="groupname">lfs</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 lfs
24useradd -s /bin/bash -g lfs -m -k /dev/null lfs</userinput></screen>

73  when logged in as <systemitem class="username">root</systemitem>, which
74  does not require the <systemitem class="username">lfs</systemitem> user
