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. |

32 | <para>Some host distributions use custom features in their filesystem |
---|
33 | creation tools (E2fsprogs). This can cause problems when booting into |
---|
34 | your new CLFS system, as those features will not be supported by the |
---|
35 | CLFS-installed E2fsprogs; you will get an error similar to |
---|
36 | <computeroutput>unsupported filesystem features, upgrade your |
---|
37 | e2fsprogs</computeroutput>. To check if your host system uses custom |

38 | enhancements, run the following command:</para> |

43 | large_file; resize_inode or sparse_super then your host system may have custom |

44 | enhancements. In that case, to avoid later problems, you should compile the |
---|
45 | stock E2fsprogs package and use the resulting binaries to re-create the |
---|
46 | filesystem on your CLFS partition. To do this, run the following commands |
