Interesting.

Note that what you describe should also be the case if using a regular
container

 sudo lxc-create -t ubuntu-cloud -n u1
 sudo lxc-start -n u1

Is the process group of init somehow ending up different in the user
namespace case? Or else why would this only be a problem in the
user namespace case?
