<listitem><para>Lastly, the patch also fixes a problem that causes
statically linked binaries to crash that were linked against Glibc-2.2
libraries. This patch is only needed temporarily because we have static
programs in <filename class="directory">/static/bin</filename> that might
be linked against an older Glibc version (the one from the host
distribution). We will install Glibc again at the end of this chapter to
remove this patch so you'll have a pristine Glibc as the developers

<listitem><para>It fixes a problem that causes statically linked binaries
to crash that were linked against Glibc-2.2 libraries. Even though static
binaries have all the necessary parts of Glibc built-in, they still rely
on one external library: Glibc's NSS libraries. These libraries, among
other things, tell programs where the system's password database is
(/etc/password, or NIS, or whatever other scheme has been
configured).</para>
<para>Glibc has undergone some changes since version
2.2.x and the new NSS code is incompatible with the old one. So when Glibc
is installed, it will install its new NSS libraries and static programs
will load these new NSS libraries and start to abort with
<emphasis>segmentation faults</emphasis>. This patch undoes a few of the
changes to overcome the problem.</para>
