| 10 | <para>Now that a blank partition has been set up, the file system can
|
|---|
| 11 | be created. The most widely-used system in the Linux world is the
|
|---|
| 12 | second extended file system (ext2), but with newer high-capacity
|
|---|
| 13 | hard disks, journaling file systems are becoming increasingly
|
|---|
| 14 | popular. We will create an ext2 file system, however build
|

| 15 | instructions for other file systems can be found at <ulink

| 19 | <para>To create an ext2 file system on the LFS partition, run the following:</para>

| 20 |
|
|---|
| 21 | <screen><userinput>mke2fs /dev/<replaceable>[xxx]</replaceable></userinput></screen>
|

| 23 | <para>Replace <replaceable>[xxx]</replaceable> with the name of the LFS
|

| 24 | partition (<filename class="devicefile">hda5</filename> in our previous example).</para>

| 25 |
|
|---|
| 26 | <note><para>Some host distributions use custom features in their filesystem
|
|---|
| 27 | creation tools (e2fsprogs). This can cause problems when booting into your new
|
|---|
| 28 | LFS in Chapter 9, as those features will not be supported by the LFS-installed
|
|---|
| 29 | e2fsprogs; you will get an error similar to <quote>unsupported filesystem
|
|---|
| 30 | features, upgrade your e2fsprogs</quote>. To check if your host system
|
|---|
| 31 | uses custom enhancements, run the following command:</para>
|
|---|
| 32 |
|
|---|
| 33 | <screen><userinput>debugfs -R feature /dev/<replaceable>[xxx]</replaceable></userinput></screen>
|
|---|
| 34 |
|
|---|
| 35 | <para>If the output contains features other than: dir_index; filetype;
|
|---|
| 36 | large_file; resize_inode or sparse_super then your host system may have custom
|
|---|
| 37 | enhancements. In that case, to avoid later problems, you should compile the
|
|---|
| 38 | stock e2fsprogs package and use the resulting binaries to re-create the
|
|---|
| 39 | filesystem on your LFS partition:</para>
