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.
18  Instructions for other file systems can be found at
19  <ulink url="&cblfs-root;index.php?section=6#File_System"/>.</para>

21  <para os="b">To create an <systemitem class="filesystem">ext2</systemitem> file
22  system on the CLFS partition, run the following as
23  <systemitem class="username">root</systemitem>:</para>

31  <note os="e">
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>
39
40<screen os="f"><userinput>debugfs -R feature /dev/<replaceable>[xxx]</replaceable></userinput></screen>
41
42    <para>If the output contains features other than: dir_index; filetype;
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
47    as <systemitem class="username">root</systemitem>:</para>
