ok. so the process of change CellSrvDB on db servers and bos restart AND
updating (copying) new CellServDB to clients has to be done in a very
short time to minimize timeout symptoms for users, because db servers
has to be in sync and ubik coordinator has to be elected and the afs
clients with new CellServDB with the new db server (lowest ip) asks the
new db server (ubik coordinator) first.
