ceph-monstore-tool rebuild question

Hi,all I recently read the ceph-monstore-tool code, and have a question about rebuild operations. In update_paxos() we read osdmap, pgmap, auth and pgmap_pg records to pending_proposal(a bufferlist) as the value of the key paxos_1, and set paxos_pending_v=1, and set the paxos_last_committed=0 and paxos_first_committed=0; My question is if we start the mon after rebuild, let's say there is only one mon now, the mon will not commit the paxos_pending_v=1, and if we change the osdmap by 'ceph osd set noout' the new pending_v=1 will overwrite the former one in rebuild, so i think we don't need to set paxos_1=pending_proposal, paxos_pending_v=1 in 'ceph-monstore-tool rebuild'. Thanks!
