+<note><para>Some host distributions use custom features in their filesystem
+creation tools (e2fsprogs).  This can cause problems when booting into your new
+LFS in Chapter 9, as those features will not be supported by the LFS-installed
+e2fsprogs; you will get an error similar to <quote>unsupported filesystem
+features, upgrade your e2fsprogs</quote>.  To check if your host system
+uses custom enhancements, run the following command:</para>

+<screen><userinput>debugfs -R feature /dev/<replaceable>[xxx]</replaceable></userinput></screen>
+
+<para>If the output contains features other than: dir_index; filetype;
+large_file; resize_inode or sparse_super then your host system may have custom
+enhancements.  In that case, to avoid later problems, you should compile the
+stock e2fsprogs package and use the resulting binaries to re-create the
+filesystem on your LFS partition:</para>
+
+<screen><userinput>cd /tmp
+tar xjf /path/to/sources/e2fsprogs-1.36.tar.bz2
