Whenever possibly, don't try to run any end-of-life distro, as it could
open yourself to various security hole, and possibly harm others (e.g. when
your setup is compromized by botnet). Even if it's in container.

Short version: some changes are necessary to run inside a container. Newer
distro versions (e.g. xenial) has those changes built in, older ones don't.

See https://github.com/lxc/lxc/blob/master/templates/lxc-centos.in on what
some of the changes look like for a sysvinit-based distro (this includes
editing /etc/inittab).
