That's interesting!  Thanks for testing.

Title:
  login console 0 in user namespace container is not configured right

Status in “linux” source package in Trusty:

Bug description:
  When you create a container in a private user namespace, when you start the
  container without the '-d' flag, that console is not properly set up.  Logging in
  gives you

  -bash: no job control in this shell

  and hitting ctrl-c reboots the container.

  Consoles from 'lxc-console -n $container' behave correctly.

  This may be a kernel issue, as discussed here:

  http://lists.linuxcontainers.org/pipermail/lxc-
  devel/2013-October/005843.html

  so also marking this as affecting the kernel.

  This can be worked around, but really needs to be fixed before trusty
  is frozen.
