Consider the following scenario: you have three replicas, A, B, C
with one file containing "init", and each one synchronizes with the
others. A modifies the file to "foo" and syncs with B. Then B syncs
with C. So all replica are in the same state and synchronized. Now
imagine C changes the content of the file to "bar" and synchronizes
with A. Intuitively, the change should propagate, but instead a
conflict is detected, because from the point of view of unison, A and
C previously had "init" and now one has "foo" and the other "bar".
What is missing in this case is a way to propagate the
synchronization state between synchronization pairs.
I hope this makes things clearer.
