<title>Creating a File System on the Partition</title>
- <para>Now that a blank partition has been set up, the file system can be created.
- The most widely-used system in the Linux world is the second extended file
- system (<systemitem class="filesystem">ext2</systemitem>), but with newer
- high-capacity hard disks, journaling file systems are becoming increasingly
- popular. The third extended filesystem (<systemitem
- class="filesystem">ext3</systemitem>) is a widely used enhancement to
- <systemitem class="filesystem">ext2</systemitem>, which adds journaling
- capabilities and is compatible with the E2fsprogs utilities.
- We will create an <systemitem class="filesystem">ext3</systemitem>
- file system. Instructions for creating other file systems can be found at
- <ulink url="&blfs-root;view/svn/postlfs/filesystems.html"/>.</para>
+ <para>Now that a blank partition has been set up, the file system can be
+ created. LFS can use any file system recognized by the Linux kernel, but the
+ most common types are ext3 and ext4. The choice of file system can be
+ complex and depends on the characteristics of the files and the size of
+ the partition. For example:</para>

+ <listitem><para>is an upgrade to ext2 that includes a journal
