像eosio.token, eosio.ram，eosio.names等这些系统账户是怎么来的？由谁创建呢，它们有对应的私钥吗？如果有这些私钥由谁管理？

回答：

eosio.token, eosio.ram，eosio.names，由最开始的创始账号eosio创建，主网启动后，这类系统账号权限转交给了BP去管理。
可通过查看账户验证

root@iZj6cbx3duprxf6dasczbpZ:~# cleos -u http://eu1.eosdac.io get account eosio.token
permissions: 
     owner     1:    1 eosio@active, 
        active     1:    1 eosio@active, 

root@iZj6cbx3duprxf6dasczbpZ:~# cleos -u http://eu1.eosdac.io get account eosio.ram
permissions: 
     owner     1:    1 eosio@active, 
        active     1:    1 eosio@active,

root@iZj6cbx3duprxf6dasczbpZ:~# cleos -u http://eu1.eosdac.io get account eosio.names
permissions: 
     owner     1:    1 eosio@active, 
        active     1:    1 eosio@active, 

得到，账户都归属于eosio
查询eosio账户

root@iZj6cbx3duprxf6dasczbpZ:~# cleos -u http://eu1.eosdac.io get account eosio
privileged: true
permissions: 
     owner     1:    1 eosio.prods@active, 
        active     1:    1 eosio.prods@active, 

得到eosio账户归属于eosio.prods
而eosio.prods即为BP节点

root@iZj6cbx3duprxf6dasczbpZ:~# cleos -u http://eu1.eosdac.io get account eosio.prods
permissions: 
     owner     1:    
        active    15:    1 argentinaeos@active, 1 bitfinexeos1@active, 1 eos42freedom@active, 1 eosamsterdam@active, 1 eosauthority@active, 1 eosbeijingbp@active, 1 eosbixinboot@active, 1 eoscanadacom@active, 1 eosdacserver@active, 1 eosfishrocks@active, 1 eoshuobipool@active, 1 eosisgravity@active, 1 eoslaomaocom@active, 1 eosnewyorkio@active, 1 eosriobrazil@active, 1 eosswedenorg@active, 1 helloeoscnbp@active, 1 libertyblock@active, 1 starteosiobp@active, 1 teamgreymass@active, 1 zbeosbp11111@active, 
           prod.major    11:    1 argentinaeos@active, 1 bitfinexeos1@active, 1 eos42freedom@active, 1 eosamsterdam@active, 1 eosauthority@active, 1 eosbeijingbp@active, 1 eosbixinboot@active, 1 eoscanadacom@active, 1 eosdacserver@active, 1 eosfishrocks@active, 1 eoshuobipool@active, 1 eosisgravity@active, 1 eoslaomaocom@active, 1 eosnewyorkio@active, 1 eosriobrazil@active, 1 eosswedenorg@active, 1 helloeoscnbp@active, 1 libertyblock@active, 1 starteosiobp@active, 1 teamgreymass@active, 1 zbeosbp11111@active, 
              prod.minor     8:    1 argentinaeos@active, 1 bitfinexeos1@active, 1 eos42freedom@active, 1 eosamsterdam@active, 1 eosauthority@active, 1 eosbeijingbp@active, 1 eosbixinboot@active, 1 eoscanadacom@active, 1 eosdacserver@active, 1 eosfishrocks@active, 1 eoshuobipool@active, 1 eosisgravity@active, 1 eoslaomaocom@active, 1 eosnewyorkio@active, 1 eosriobrazil@active, 1 eosswedenorg@active, 1 helloeoscnbp@active, 1 libertyblock@active, 1 starteosiobp@active, 1 teamgreymass@active, 1 zbeosbp11111@active,

结论

eosio, eosio.token, eosio.ram，eosio.names等 系统账号归BP节点管理
