Well, that doesn't really work, since upstart and systemd would fight for the /sbin/init name. If we want the system to boot into systemd by default /sbin/init must be linekd to /bin/systemd. systemd provides compatibility with those sysv tools like reboot/shutdown/runlevel and init itself via symlinks to native binaries. The package "systemd" currently includes the native binaries and "systemd-sysvinit" adds in those symlinks. Only "systemd-sysvinit" conflicts with upstart, and only that package is what makes systemd the default init system. And that is the package which I want to make obsolete upstart. To achieve what you want to do upstart would need to support something similar: make it possible to install it without insisting on the /sbin/init file name and related ones, and then add in those names via symlinks only by a an upstart-sysvinit package or so. But upstart doesn't support something like that. Sorry.
