creating a node without using a ssh-config file triggers a fatal error

[pmariani]

Repro: in config.cfg, make it so that ssh-config doesn't point to a valid ssh config file (either empty configuration entry, or point to empty file). Then create a new node with fix-rackspace create. It'll fail with the following error:

Traceback (most recent call last):
  File "/usr/local/bin/fix-rackspace", line 8, in <module>
    r.main(sys.argv[1:])
  File "/usr/local/lib/python2.7/dist-packages/littlechef_rackspace/runner.py", line 191, in main
    command.execute(**args)
  File "/usr/local/lib/python2.7/dist-packages/littlechef_rackspace/commands.py", line 38, in execute
    self.chef_deploy.deploy(host=host, **kwargs)

    lc.env.ssh_config.parse(open(bootstrap_config_file))
AttributeError: 'NoneType' object has no attribute 'parse'

This is due to lc.env.ssh_config being set to None in littlechef when no valid ssh-config file is used

Thanks for the report, I'll take a look this weekend.
