BOM error updating hostname on centos6.x

Seeing the following:

Jul 14 15:42:38 cent6-example [CLOUDINIT] util.py[DEBUG]: Failed to update the hostname to cent6-example.cloud.phx3.gdg (cent6-example)#012Traceback (most recent call last):#012 File "/usr/lib/python2.6/site-packages/cloudinit/config/cc_update_hostname.py", line 39, in handle#012 cloud.distro.update_hostname(hostname, fqdn, prev_fn)#012 File "/usr/lib/python2.6/site-packages/cloudinit/distros/__init__.py", line 214, in update_hostname#012 prev_hostname = self._read_hostname(prev_hostname_fn)#012 File "/usr/lib/python2.6/site-packages/cloudinit/distros/rhel.py", line 172, in _read_hostname#012 (_exists, contents) = rhel_util.read_sysconfig_file(filename)#012 File "/usr/lib/python2.6/site-packages/cloudinit/distros/rhel_util.py", line 64, in read_sysconfig_file#012 return (exists, SysConf(contents))#012 File "/usr/lib/python2.6/site-packages/cloudinit/distros/parsers/sys_conf.py", line 61, in __init__#012 write_empty_values=True)#012 File "/usr/lib/python2.6/site-packages/configobj.py", line 1219, in __init__#012 self._load(infile, configspec)#012 File "/usr/lib/python2.6/site-packages/configobj.py", line 1272, in _load#012 infile = self._handle_bom(infile)#012 File "/usr/lib/python2.6/site-packages/configobj.py", line 1422, in _handle_bom#012 if not line.startswith(BOM):#012UnicodeDecodeError: 'ascii' codec can't decode byte 0xff in position 0: ordinal not in range(128)

$ rpm -qa | grep configobj
python-configobj-4.6.0-3.el6.noarch

This might be fixed in a newer configobj (probably is) but just wanted to note this here.
