In illumos, a descendant of (Open)Solaris, we have a first class container primitive called "zones". In SmartOS, the Joyent-backed distribution of illumos, we also have support for running an entire Linux userland (e.g. Ubuntu or CentOS) in this substrate.

You can have the best of both worlds: a secure container substrate, designed from the ground up as a coherent whole like Jails; and the vast packaging ecosystem provided by Ubuntu.
