=== Security issue with backups after re-flashing XOs ===
+
+
The usecase:
+
+
* a XO registered on a school server;
+
* processed several Journal backups there;
+
* got re-flashed with not keeping client side identities, like Sugar profile private key;
+
* the XO wants to restore Journal content from previous backups, but from school server point of view, it is regular registration request from new XO that provide the same serial number that existing registration uses.
