Dear Daniel,
You said "use a real init system like systemd to spawn off the things", do you
mean a full OS distro container?
I installed the container using "yum --installroot=/root/fedora19lxc --releasever=19
install -y openssh, bridge-utils" which is described at
https://www.redhat.com/archives/libvirt-users/2013-August/msg00007.html.
I don't know how to make systemd work in my current container.
And I don't know how to install a full OS distro container
either. Could you give me more guidance?
If you install a modern Fedora distro in a chroot and use that as the
filesystem for the container, then you have a container that uses
systemd for startup. There is nothing special you should ned todo with
system - it ought to "just work" as systemd is designed to easily cope
with running inside a container. For reference see also this:
