My ideas is:

• cd ~/path/to/project
• ./fdump --output /tmp/config.json or ./fdump --output --backup=.old /tmp/config.json
• scp config.json cluster:/tmp/
• ssh cluster-jail-x 'sudo ./fdump --input < /tmp/config.son'
• LT: client/server ala zookeeper with push/pop ?
• looks config file and profit :)
