Description of problem:
I keep my own .cfg files local so they are easy to edit.  Because of this, I use
the --configdir option.  If you are using a different config directory, upgrade
mock, and don't notice that it now needs a logging.ini, you get:

INFO: mock suid wrapper version 0.8.4 
ERROR:root:No section: 'formatters'
Traceback (most recent call last):
  File "/usr/libexec/mock.py", line 333, in <module>
    main(retParams)
  File "/usr/libexec/mock.py", line 239, in main
    logging.config.fileConfig(os.path.join(config_path,
config_opts["log_config_file"]))
  File "/usr/lib/python2.5/logging/config.py", line 76, in fileConfig
    formatters = _create_formatters(cp)
  File "/usr/lib/python2.5/logging/config.py", line 107, in _create_formatters
    flist = cp.get("formatters", "keys")
  File "/usr/lib/python2.5/ConfigParser.py", line 511, in get
    raise NoSectionError(section)
NoSectionError: No section: 'formatters'

Why can't it just say:
ERROR: ~/myconfigdir/logging.ini not found

Version-Release number of selected component (if applicable):
