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.
