+    If you are sharing a <filename class="directory">/home</filename>
+    or <filename class="directory">/usr/src</filename> with another
+    Linux distro (for example, the host distro used for building LFS), you
+    can create a user with the same UID (and, same primary group GID) to
+    keep the file ownership consistent across the systems.  First, on
+    <emphasis>the other distro</emphasis>, get the UID of the user and the
+    GID of the user's primary group:

+    The command should output the UID and GID, separated by a colon.  Now
+    on the BLFS system, create the primary group and the user:
