[PATCH] Improper initrd failure message at boot time 

On system boot up, there was an failure reported to boot.msg:

     <5>Trying to move old root to /initrd ... failed

According to initrd(4) man page, step #7 of BOOT-UP OPERATION
is described as below:
          7. If the normal root file has directory /initrd, device
          /dev/ram0 is moved from  /  to  /initrd.   Otherwise  if
          directory  /initrd  does  not  exist device /dev/ram0 is
          unmounted.

We got service calls from customers concerning about this failure message
at boot time.  Many systems do not have /initrd and thus the message can be
changed in the case of non-existing /initrd so that it does not sound like
a failure of the system.
