Sounds good, one scenario is missing.
disconnect (same same)
ass-* the node which would be SyncTarget needs to crash
itself to 'clear' the higher levels, and then would
(after the reboot) go through the first scenario.
This may be useful for unattended embedded scenarios, but as it is
pretty severe recovery for a grave error, may even value an additional
