+An other way for this step is to edit /boot/grub/menu.lst and change the 
+line for the first kernel by adding "rw rd.convertfs" (without the 
+quotes) and removing "splash quiet" (optionnal)
+
+After the reboot (and the /usr conversion), you need to rollback your 
+changes.

+> If you want to see things in more depth, you can also add
