| 13 | <para os="a">Now that a blank partition has been set up, the file system can be

| 14 | created. The most widely-used system in the Linux world is the second
|
|---|
| 15 | extended file system (ext2), but with newer high-capacity hard disks,
|
|---|
| 16 | journaling file systems are becoming increasingly popular. We will create
|

| 17 | an <systemitem class="filesystem">ext2</systemitem> file system.

| 31 | <para>Some host distributions use custom features in their filesystem
|
|---|
| 32 | creation tools (E2fsprogs). This can cause problems when booting into
|
|---|
| 33 | your new CLFS system, as those features will not be supported by the
|
|---|
| 34 | CLFS-installed E2fsprogs; you will get an error similar to
|
|---|
| 35 | <computeroutput>unsupported filesystem features, upgrade your
|

| 36 | e2fsprogs</computeroutput>. To check if your host system uses custom
|

| 41 | <para>If the output contains features other than: dir_index; filetype;
|
|---|
| 42 | large_file; resize_inode or sparse_super then your host system may have custom
|
|---|
| 43 | enhancements. In that case, to avoid later problems, you should compile the
|

| 44 | stock E2fsprogs package and use the resulting binaries to re-create the
