    1111  <title>Creating a File System on the Partition</title>

    13   <para>Now that a blank partition has been set up, the file system can be created.
    14   The most widely-used system in the Linux world is the second extended file
    15   system (<systemitem class="filesystem">ext2</systemitem>), but with newer
    16   high-capacity hard disks, journaling file systems are becoming increasingly
    17   popular. The third extended filesystem (<systemitem
    18   class="filesystem">ext3</systemitem>) is a widely used enhancement to
    19   <systemitem class="filesystem">ext2</systemitem>, which adds journaling
    20   capabilities and is compatible with the E2fsprogs utilities.
    21   We will create an <systemitem class="filesystem">ext3</systemitem>
    22   file system. Instructions for creating other file systems can be found at
    23   <ulink url="&blfs-root;view/svn/postlfs/filesystems.html"/>.</para>
     13  <para>Now that a blank partition has been set up, the file system can be
     14  created.  LFS can use any file system recognized by the Linux kernel, but the
     15  most common types are ext3 and ext4.  The choice of file system can be
     16  complex and depends on the characteristics of the files and the size of
     17  the partition.  For example:</para>
    2418
    25   <para>To create an <systemitem class="filesystem">ext3</systemitem> file
    26   system on the LFS partition, run the following:</para>
     19  <variablelist>
     20    <varlistentry>
     21      <term>ext2</term>
     22      <listitem><para>is suitable for small partitions that are updated infrequently
     23      such as /boot.</para>
     24      </listitem>
     25    </varlistentry>
     26    <varlistentry>
     27      <term>ext3</term>
     28      <listitem><para>is an upgrade to ext2 that includes a journal
     29      to help recover the partition's status in the case of an unclean
     30      shutdown.  It is commonly used as a general purpose file system.

     32      </listitem>

     34    <varlistentry>
     35      <term>ext4</term>
     36      <listitem><para>is the latest version of the ext file system family of
     37      partition types.  It provides several new capabilties including
     38      nano-second timestamps, creation and use of very large files (16 TB), and
     39      speed improvements.</para>

     44  <para>Other file sytems, including FAT32, NTFS, ReiserFS, JFS, and XFS are
     45  useful for specialized purposes.  More information about these file systems
