          If you left the chroot environment to create a backup or restart
          building using a restore, remember to check that the virtual
          file systems are still mounted (<command>findmnt | grep
-         $LFS</command>).  If they are not mounted, remount them now as
+         $LFS</command> should show at least
+         <filename class="directory">$LFS/dev</filename>,
+         <filename class="directory">$LFS/proc</filename>, and
+         <filename class="directory">$LFS/sys</filename> as mounted).
+         If they are not mounted, remount them now as
          described in <xref linkend='ch-tools-kernfs'/> and re-enter the chroot
          environment (see <xref linkend='ch-tools-chroot'/>) before continuing.
