[ghost]

Describe the bug (描述bug)
使用命令 ansible-playbook -i server.ini deploy_curve.yml 进行部署的时候，提示

TASK [generate_config : generate configuration file directly] *************************************************************************************************
fatal: [localhost]: FAILED! => {"changed": false, "checksum": "27c7b68395f392cdc4d364ba6afa06b577c925ff", "msg": "Destination /etc/curve not writable"}

。。。。。。。。。。。
fatal: [localhost]: FAILED! => {"changed": true, "cmd": "sudo cp /etc/curve/etcd.conf.yml /etc/curve/etcd.conf.yml.bak", "delta": "0:00:00.064517", "end": "2021-02-21 09:41:20.241484", "msg": "non-zero return code", "rc": 1, "start": "2021-02-21 09:41:20.176967", "stderr": "cp: cannot stat '/etc/curve/etcd.conf.yml': No such file or directory", "stderr_lines": ["cp: cannot stat '/etc/curve/etcd.conf.yml': No such file or directory"], "stdout": "", "stdout_lines": []}

然后失败无法部署。

To Reproduce (复现方法)

1. 删除 etc/curve 可复现这种情况。 ansiable 与 rm 操作都在root用户下进行

2. 根据提示把 etc/curve 目录拥有者改成curve后没有这个报错。

   chown -R curve:curve /etc/curve
