Containers don't boot from an image like Xen and KVM do. You can think of containers as a way of encapsulating a process or a group of processes. So the init_path for a container needs to be a process or a group of processes you can run inside the container.
Something to try would be to create a script and run something like exec /bin/bash in the script.
I'm not sure what to run inside the container. May I fill it optionally now?
If you're not sure how something is support to work, please ask questions instead of sending a patch. You should only send patches if you understand what the patch needs to do. If you aren't sure if a patch is correct, it's okay to send it as an RFC (RFC means "Request For Comments"). In this case, it sounds like you aren't sure how containers work. And that's alright. However, if you are confused about something, it's not a problem to send an e-mail (you can email me privately or send an e-mail to cimtest-devel@opensource.ibm.com). If you want, we can even set up a time to meet on IRC to discuss any questions you have. Thanks! -- Kaitlin Rupert IBM Linux Technology Center kaitlin@linux.vnet.ibm.com
