The operator can create and install whatever configuration file is
necessary on the cold spare host and start the failed services. The
HotSpareDataService (etc.) idea is for the automated approach without
SMS synchronization.

Would you consider changing the startup mechanism to a simple, per
host configuration, non-synchronizing mechanism?
