Comment 1 for bug 1550770

This test fails on centos because of the losetup / path issue:
[LOG] 0:10.940 ERROR juju.container.lxc failed to detach loop devices from lxc container: listing loop devices: exec: "losetup": executable file not found in $PATH

It fails on other series /arches because it cannot find tools to start the container with:
[LOG] 0:06.101 ERROR juju.provisioner cannot start instance for machine "0/lxc/0": need tools for arch arm64, only found [amd64]

This happens because we seed the tools with the current series / arch, but use the default series when creating a container ("trusty"). We need to add the trusty tools for the current arch.
