-        <para>If Glibc needs to be upgraded to a newer version, (e.g.  from
-        glibc-2.31 to glibc-2.32), it is safer to rebuild LFS.  Though you

+        <para>If Linux kernel needs to be upgraded (for example, from
+        5.10.17 to 5.10.18 or 5.11.1), nothing else need to be rebuilt.
+        The system will keep working fine thanks to the well-defined border
+        between kernel and userspace.  Specifically, Linux API headers
+        need not to be (and should not be, see the next item) upgraded
+        alongside the kernel.  You'll need to reboot your system to use the
+        upgraded kernel.</para>
