Details:

running jk_init at the first time throws below exception:


$ sudo jk_init -j /home/testjail2 jk_lsh -f                
ERROR: cannot lstat() /home/testjail2                      
/home                                                      
Creating jail /home/testjail2                              
Traceback (most recent call last):                         
  File "/usr/local/sbin/jk_init", line 246, in <module>    
    main()                                                 
  File "/usr/local/sbin/jk_init", line 243, in main        
    activateConfig(config, jail, args)
  File "/usr/local/sbin/jk_init", line 163, in activateConfig
    ji.handle_cfg_section(config,jail,cfg,section)
  File "/usr/local/sbin/jk_init", line 98, in handle_cfg_section
    self.handle_cfg_section(config,chroot,cfg,tmp)
  File "/usr/local/sbin/jk_init", line 133, in handle_cfg_section
    jk_lib.init_passwd_and_group(chroot,users,groups,config['verbose'])
  File "/usr/local/share/jailkit/jk_lib.py", line 738, in
init_passwd_and_group
    create_parent_path(chroot,'/etc/', be_verbose, copy_permissions=0,
allow_suid=0, copy_ownership=0)
  File "/usr/local/share/jailkit/jk_lib.py", line 445, in create_parent_path
    os.mkdir(jailpath, 0755)
OSError: [Errno 17] File exists: '/home/testjail2/etc/'

running it a second time, it works as expected.

Appended patch fixes the problem for me. However, I'm not perfectly sure
whether this is the right way to fix it.
I ran into the same problem on SLES 11 and OpenBSD.

patch is against jailkit-2.11
