Question

我正在尝试使用cloud-init脚本设置我的Bluemix VM的主机名，但它引发了错误：

cloud-init[1143]: Cloud-init v. 0.7.5 running 'init' at Sun, 27 Sep 2015 13:14:39 +0000. Up 66.82 seconds.

CentOS Linux 7 (Core)

localhost login: cloud-init[1143]: 2015-09-27 13:15:07,239 - util.py[WARNING]: Failed to set the hostname to XXXXXXXXX (XXXX)
cloud-init[1143]: 2015-09-27 13:15:07,258 - util.py[WARNING]: Running set_hostname (<module 'cloudinit.config.cc_set_hostname' from '/usr/lib/python2.7/site-packages/cloudinit/config/cc_set_hostname.pyc'>) failed
cloud-init[1143]: 2015-09-27 13:15:32,287 - util.py[WARNING]: Failed to write hostname XXXXXXXXX to /var/lib/cloud/data/previous-hostname

登录服务器，我可以看到/var/lib/cloud/data/previous-hostname不存在：

[ibmcloud@host-192-168-0-30 ~]$ ls -lh /var/lib/cloud/data/previous-hostname
ls: cannot access /var/lib/cloud/data/previous-hostname: No such file or directory

/usr/lib/python2.7/site-packages/cloudinit/config/cc_set_hostname.py中的代码看起来非常简单：

from cloudinit import util


def handle(name, cfg, cloud, log, _args):
    if util.get_cfg_option_bool(cfg, "preserve_hostname", False):
        log.debug(("Configuration option 'preserve_hostname' is set,"
                    " not setting the hostname in module %s"), name)
        return

    (hostname, fqdn) = util.get_hostname_fqdn(cfg, cloud)
    try:
        log.debug("Setting the hostname to %s (%s)", fqdn, hostname)
        cloud.distro.set_hostname(hostname, fqdn)
    except Exception:
        util.logexc(log, "Failed to set the hostname to %s (%s)", fqdn,
                    hostname)
        raise

可能导致此错误的原因是什么？是否可以提供我自己的cc_set_hostname.py脚本版本，我可以添加其他调试来转储Exception？

cloud-init：无法将主机名XXXX写入/ var / lib / cloud / data / previous-hostname
