Comment 1 for bug 1422681

Dimitri and I discussed that this morning. It's really hairy to move a lot of conffiles from one package to another. We resolved to this:

 * Split out upstart-sysv with just /sbin/init, reboot, etc. (similar to systemd-sysv)
 * Keep the config files in upstart
 * change init to depend on systemd-sysv | upstart-sysv
 * change systemd to conflict to upstart-sysv instead
 * make upstart depends: init, to ensure that we never lose an init system during upgrade
