All,

          I recently had to move /usr on a machine.  Since moving /usr
when i boot the machine I get this message immediately after the bios
prompts are finished and before the boot process starts "error: file
not found".  After the machine comes up all appears to work normally.
I will now explain what i did to move /usr.

  1) log in as root unmount /home
  2) resize /home
  3) create new partition in newly created free space
  4) edit fstab to mount new partition as /usr2
  5) reboot
  6) run rsync -a /usr/ /usr2
  7) run diff /usr /usr2 to ensure they are the same
  8) edit fstab to mount new partition as /usr instead of /usr2
  9) run mv /usr /usr3
10) reboot
11) get error but all appears to work correctly
