| 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>

| 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.
|

| 31 | </para>

| 32 | </listitem>
|

| 33 | </varlistentry>
|

| 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 capabilities including
|
|---|
| 38 | nano-second timestamps, creation and use of very large files (16 TB), and
|
|---|
| 39 | speed improvements.</para>

|

|

| 43 |
|
|---|
| 44 | <para>Other file systems, including FAT32, NTFS, ReiserFS, JFS, and XFS are
|
|---|
| 45 | useful for specialized purposes. More information about these file systems
|
|---|
| 46 | can be found at <ulink

|

|

| 49 | <para>LFS assumes that the root file system (/) is of type ext4. To create
|
|---|
| 50 | an <systemitem class="filesystem">ext4</systemitem> file system on the LFS
|
|---|
| 51 | partition, run the following:</para>
|
|---|
| 52 |
|
|---|
| 53 | <screen role="nodump"><userinput>mkfs -v -t ext4 /dev/<replaceable><xxx></replaceable></userinput></screen>
|
|---|
| 54 |
|
|---|
| 55 | <para>Replace <replaceable><xxx></replaceable> with the name of the LFS
|
|---|
| 56 | partition.</para>
|
|---|
| 57 |
|
|---|
| 58 | <para>If you are using an existing <systemitem class="filesystem">swap
|
|---|
| 59 | </systemitem> partition, there is no need to format it. If a new
|
|---|
| 60 | <systemitem class="filesystem"> swap</systemitem> partition was created,
|
|---|
| 61 | it will need to be initialized with this command:</para>
|
|---|
| 62 |
|
|---|
| 63 | <screen role="nodump"><userinput>mkswap /dev/<replaceable><yyy></replaceable></userinput></screen>
|
|---|
| 64 |
|

| 65 | <para>Replace <replaceable><yyy></replaceable> with the name of the
|
|---|
| 66 | <systemitem class="filesystem">swap</systemitem> partition.</para>
