    5453  <para>After we build our <quote>Cross-Tools</quote>, we start building
    5554  a very minimal working system in
    56   <filename class="directory">/tools</filename>. This minimal system will be
    57   built using the cross-toolchain in
    58   <filename class="directory">/cross-tools</filename>.</para>
     55  <filename class="directory">/tools</filename>, using the cross-toolchain in
     56  <filename class="directory">/cross-tools</filename>. Once the temporary
     57  system is finished, we perform a few additional tasks to prepare to
     58  enter this temporary build environment, either by booting or chrooting into
     59  it. For more details about the difference between these methods, see
     60  <xref linkend="ch-temp-system-choose"/>.</para>
    5961
    60   <para>In <xref linkend="chapter-building-system"/>, the full CLFS system is
    61   built. Depending on the system you are cross-compiling for, you will either
    62   boot the minimal temp-system on the target machine, or chroot into it.</para>
    63 
    64   <para>The <command>chroot</command> (change root) program is used to enter
    65   a virtual environment and start a new shell whose root directory will be set
    66   to the CLFS partition. This is very similar to rebooting and instructing the
    67   kernel to mount the CLFS partition as the root partition.
    68   The major advantage is that <quote>chrooting</quote> allows the builder to
    69   continue using the host while CLFS is being built. While waiting for package
    70   compilation to complete, a user can switch to a different virtual console
    71   (VC) or X desktop and continue using the computer as normal.</para>
    72 
    73   <para>Some systems cannot be built by chrooting so they must be
    74   booted instead. Generally, if you building for a different arch than
    75   the host system, you must reboot because the kernel will likely not
    76   support the target machine. Booting involves installing a few
    77   additional packages that are needed for bootup, installing
    78   boot-scripts, and building a miminal kernel.<!-- We also describe some
    79   alternative booting methods in <xref linkend="ch-boot-whatnext"/> --></para>
     62  <para>In <xref linkend="chapter-building-system"/>, after having booted
     63  or chrooted into the temporary build environment, the full CLFS system is
     64  built.</para>
    8065
    8166  <para>To finish the installation, several configuration files are created in
    82   <xref linkend="chapter-system-config"/>, and the kernel and boot loader are set
    83   up in <xref linkend="chapter-bootable"/>. <xref linkend="chapter-finalizing"/>
     67  <xref linkend="chapter-system-config"/>, and the kernel and boot loader are
     68  set up in <xref linkend="chapter-bootable"/>.
