With "there was no change" meant: No administrator did change the file; if a
package installation changed the file, I'm not aware of it.

So it's this phrase from the manual page?:

              WARNING:  The  clusters  behavior is undefined if this option
is
              enabled on only a subset of the cluster (for  example  during 
a
              rolling upgrade).

BTW: The manual page does not says that "nodeid" has to be a positive 32-bit
2-complement; the page just says it's a 32-bit number...
