Thanks Jamie, i now better understand how to manage these containers.
So i added an exception like said, then added a new domain "<kernel>
/path/to/container/sbin/init" and set it to learning mode. Made the
container reboot, have activities but the domain doesn't list anything and
in the process view init is still listed as <kernel> /sbin/init

Do i have to do something else? Reload anything?


Thanks,

Olivier
