The purpose of the test was to check if your *host* system has a
modified e2fsprogs, which means that when you create your LFS
partition using that modified software you may run into problems when
in chroot, as we won't have those same modifications with the LFS
installation of e2fsprogs. As long as you don't have *more* that the
feature set listed, your okay. This could perhaps indicate the wording
of the paragraph could use some adjustment.
