awakened by your call for testing, I've done just that (source code fresh from 
CVS from a few minutes ago). There are still a few errors. Here was my testing 
procedure:

1. useradd -m -g users jailtest
2. passwd jailtest
3. Login with jailtest, test a little, create some files. directory listing:
drwxr-xr-x  3 jailtest users 4096 10. Nov 19:21 .
drwxr-xr-x  7 root     root  4096 10. Nov 19:15 ..
-rw-------  1 jailtest users  173 10. Nov 19:20 .bash_history
-rw-r--r--  1 jailtest users  240 10. Nov 19:15 .bash_logout
-rw-r--r--  1 jailtest users  308 10. Nov 19:15 .bash_profile
-rw-r--r--  1 jailtest users 1301 10. Nov 19:15 .bashrc
-rw-r--r--  1 jailtest users    0 10. Nov 19:15 .keep
drwxr-xr-x  5 jailtest users 4096 10. Nov 19:15 .maildir
-rw-r--r--  1 jailtest users 1466 10. Nov 19:15 .tcsh.config
-rw-r--r--  1 root     root    13 10. Nov 19:20 testbyroot.txt
-rw-r--r--  1 jailtest users    5 10. Nov 19:19 test.txt
-rw-------  1 jailtest users  701 10. Nov 19:21 .viminfo
-rw-------  1 jailtest users   52 10. Nov 19:21 .xauthVqwSJN
3. mkdir /srv/jaily
4. jk_init -v /srv/jaily basicshell

now the interesting bit:
5a. jk_jailuser -j /srv/jaily -v -n -s /bin/bash -m
this really fooled me for a moment, because no output was produced, not even an 
error message about forgetting the username ;-)

5b. next try was:
myhost cvs-src # jk_jailuser -j /srv/jaily -v -n -s /bin/bash -m jailtest
Traceback (most recent call last):
  File "/usr/sbin/jk_jailuser", line 248, in ?
    main()
  File "/usr/sbin/jk_jailuser", line 239, in main
    jailuser(jail, username, movehome, config)
UnboundLocalError: local variable 'movehome' referenced before assignment

5c. after editing /usr/sbin/jk_jailuser to include the else:
if (config['movehome'] == -1):
        movehome = getmovehome(jail, username, config)
else:
        movehome = config['movehome']
jailuser(jail, username, movehome, config)

5d. I get:
myhost cvs-src # jk_jailuser -j /srv/jaily -v -s /bin/bash -m jailtest
adding user jailtest to /srv/jaily/etc/passwd with shell /bin/bash
adding group users to /srv/jaily/etc/group
modify user jailtest; dir /srv/jaily/./home/jailtest/ and shell 
/usr/sbin/jk_chrootsh
creating directory /srv/jaily/./home/jailtest
moving files from /home/jailtest/ to /srv/jaily/./home/jailtest/
Traceback (most recent call last):
  File "/usr/sbin/jk_jailuser", line 250, in ?
    main()
  File "/usr/sbin/jk_jailuser", line 241, in main
    jailuser(jail, username, movehome, config)
  File "/usr/sbin/jk_jailuser", line 146, in jailuser
    os.rename(pw[5], newhome)
OSError: [Errno 18] Invalid cross-device link

5e. I'll try figuring out this problem later this evening.

Cheers,
Stephen
