Hi Daniel,

I want to run my application on fedora as a container and use the libraries
(/lib, /usr/lib) from the host (so my application container size is small).
I did lxc-create but lxc-execute failed (I had sent a mail earlier on this).
Suggestion was to use lxc-start itself and run as system container.

I changed the fstab file and could share the lib directory.

Please let me know if there are better solution for my use case. I would
like to try it too.

Thanks,

-Nirmal
