   I would suggest the following...  First, drop down to single-user   
   maintenance mode, i.e. runlevel 1 [*].  At this point, you are the root   
   user - you may need to supply the root password, depending on the   
   security level settings for your local system.   
      
   A trick I've picked up from "The Definitive Guide To Mandrake Linux 9.2"   
   is to use the following command, provided that the new filesystem is   
   mounted where you say it is. ;-)   
      
       (cd /usr && tar cf - .) | (cd /newusr && tar xpvf -)   
      
   Next, proceed to editing /etc/fstab and delete the contents of the old   
   /usr, as follows:   
      
      cd / && rm -rf /usr/*   
      
   Next, put the new /usr filesystem in place in the tree...   
      
      umount /newusr && mount /dev/sda12 /usr && rmdir /newusr   
      
   Now you can return to your normal runlevel [*], and you didn't even have   
   to reboot, let alone use a live/rescue CD/DVD. ;-)   
      
      
   [*] You will have to use the systemd-specific method for changing   
       runlevels, as Mandriva isn't using the old System V init system   
       anymore.  I believe that...   
      
            man systemctl   
      
       ... could possibly shed some enlightenment on the situation. ;-)
