hmm I cannot reproduce this.

did the directory /home/testjail2 exist before the command or not?

hmm your patch makes the error message go away, but the code shouldn't be executed if the directory already exists...

I'll have to test this

running jk_init at the first time throws below exception:

$ sudo jk_init -j /home/testjail2 jk_lsh -f
ERROR: cannot lstat() /home/testjail2
Creating jail /home/testjail2
Traceback (most recent call last):

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
