[1b20267] | 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. We will create an <systemitem class="filesystem">ext2</systemitem>
|

| 18 | file system. Build instructions for other file systems can be found at

|
---|
| 31 | <para>Some host distributions use custom features in their filesystem
|
---|
| 32 | creation tools (E2fsprogs). This can cause problems when booting into your new
|
---|
| 33 | LFS in Chapter 9, as those features will not be supported by the LFS-installed
|
---|
| 34 | E2fsprogs; you will get an error similar to <quote>unsupported filesystem
|
---|
| 35 | features, upgrade your e2fsprogs</quote>. To check if your host system
|
---|
| 36 | uses custom enhancements, run the following command:</para>
|
---|
[d6b76b1] | 37 |
|
---|
[2c5e4d5] | 38 | <screen role="nodump"><userinput>debugfs -R feature /dev/<replaceable>[xxx]</replaceable></userinput></screen>

[d6b76b1] | 39 |

[1b20267] | 40 | <para>If the output contains features other than: <option>dir_index</option>;
|
---|
| 41 | <option>filetype</option>; <option>large_file</option>;
|
---|
| 42 | <option>resize_inode</option> or <option>sparse_super</option> then your host
|
---|
| 43 | system may have custom enhancements. In that case, to avoid later problems,
|
---|
| 44 | you should compile the stock E2fsprogs package and use the resulting binaries
|
---|
| 45 | to re-create the filesystem on your LFS partition:</para>
