 I had BIND 10 1.0.0 installed on Debian 6. I had then updated Debian to
 Version 7.

 After the update, BIND 10 was not working anymore. The error message was:

 root at m3:~# bind10
 /usr/local/sbin/bind10: 8: exec: /usr/local/libexec/bind10/b10-init: not
 found

 The problem was the shebang line:
 #!/usr/bin/python3.1

 while I could solve this issue by re-compiling BIND 10, it might be a
 stubling block for DNS admins.

 Proposal:

 make the "bind10" start script intelligent to check the python3 version
 and

 a) if no suitable python version found, give a good error message

 b) if an version is found that could lead to issues, log a warning

 c) update the BIND 10 python modules (maybe via a wrapper or setting a
 environment variable) and start BIND 10
