  <title>Mounting the New Partition</title>

  <para>Now that a file system has been created, the partition needs to
  be made accessible. In order to do this, the partition needs to be
  mounted at a chosen mount point. For the purposes of this book, it is
  assumed that the file system is mounted under the directory specified by the
  <envar>LFS</envar> environment variable as described in the previous section.
  </para>

  <para>Create the mount point and mount the LFS file system by running:</para>

<screen role="nodump"><userinput>mkdir -pv $LFS
mount -v -t ext4 /dev/<replaceable>&lt;xxx&gt;</replaceable> $LFS</userinput></screen>

  <para>Replace <replaceable>&lt;xxx&gt;</replaceable> with the designation of the LFS
  partition.</para>

  <para>If using multiple partitions for LFS (e.g., one for <filename
  class="directory">/</filename> and another for <filename
  class="directory">/usr</filename>), mount them using:</para>

<screen role="nodump"><userinput>mkdir -pv $LFS
mount -v -t ext4 /dev/<replaceable>&lt;xxx&gt;</replaceable> $LFS
mkdir -v $LFS/usr
mount -v -t ext4 /dev/<replaceable>&lt;yyy&gt;</replaceable> $LFS/usr</userinput></screen>

  <para>Replace <replaceable>&lt;xxx&gt;</replaceable> and
  <replaceable>&lt;yyy&gt;</replaceable> with the appropriate partition
  names.</para>

  <para>Ensure that this new partition is not mounted with permissions that are
  too restrictive (such as the <option>nosuid</option> or
  <option>nodev</option> options). Run the <command>mount</command> command
  without any parameters to see what options are set for the mounted LFS
  partition. If <option>nosuid</option> and/or <option>nodev</option> are set,
  the partition will need to be remounted.</para>

  <warning><para>The above instructions assume that you will not be restarting
  your computer throughout the LFS process.  If you shut down your system,
  you will either need to remount the LFS partition each time you restart 
  the build process or modify your host system's /etc/fstab file to automatically 
  remount it upon boot.  For example:

<screen role="nodump">/dev/<replaceable>&lt;xxx&gt;</replaceable>  /mnt/lfs ext4   defaults      1     1</screen>

  If you use additional optional partitions, be sure to add them also.

  </para></warning>


  <para>If you are using a <systemitem
  class="filesystem">swap</systemitem> partition, ensure that it is enabled
  using the <command>swapon</command> command:</para>

<screen role="nodump"><userinput>/sbin/swapon -v /dev/<replaceable>&lt;zzz&gt;</replaceable></userinput></screen>

  <para>Replace <replaceable>&lt;zzz&gt;</replaceable> with the name of the
  <systemitem class="filesystem">swap</systemitem> partition.</para>

  <para>Now that there is an established place to work, it is time to
  download the packages.</para>
