- <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. 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>
- <variablelist>
- <varlistentry>
- <term>ext2</term>
- <listitem><para>is suitable for small partitions that are updated infrequently
- such as /boot.</para>
- </listitem>
- </varlistentry>
- <varlistentry>
- <term>ext3</term>
- <listitem><para>is an upgrade to ext2 that includes a journal
- to help recover the partition's status in the case of an unclean
- shutdown. It is commonly used as a general purpose file system.
- </para>
- </listitem>
- </varlistentry>
- <varlistentry>
- <term>ext4</term>
- <listitem><para>is the latest version of the ext file system family of
- partition types. It provides several new capabilities including
- nano-second timestamps, creation and use of very large files (16 TB), and
- speed improvements.</para>
- </listitem>
- </varlistentry>
- </variablelist>
- <para>Other file systems, including FAT32, NTFS, ReiserFS, JFS, and XFS are
- useful for specialized purposes. More information about these file systems
- can be found at <ulink
- url="http://en.wikipedia.org/wiki/Comparison_of_file_systems"/>.</para>
- <para>LFS assumes that the root file system (/) is of type ext4. To create
- an <systemitem class="filesystem">ext4</systemitem> file system on the LFS
- partition, run the following:</para>
- <screen role="nodump"><userinput>mkfs -v -t ext4 /dev/<replaceable><xxx></replaceable></userinput></screen>
- <para>Replace <replaceable><xxx></replaceable> with the name of the LFS
- partition.</para>
- <para>If you are using an existing <systemitem class="filesystem">swap
- </systemitem> partition, there is no need to format it. If a new
- <systemitem class="filesystem"> swap</systemitem> partition was created,
- it will need to be initialized with this command:</para>
- <screen role="nodump"><userinput>mkswap /dev/<replaceable><yyy></replaceable></userinput></screen>
- <para>Replace <replaceable><yyy></replaceable> with the name of the
- <systemitem class="filesystem">swap</systemitem> partition.</para>
