The package systemd-sysv should only break/replace sysvinit-core and not 
sysvinit (see bug #733240), which would solve bug #645540 as well.

After that gnome-shell and gdm3 should add a recommendation for 
systemd-sysv, since most people will want to use the functionality like 
suspend from menus, that needs systemd as PID 1, but occasionally some 
people may prefer to use sysvinit-core or upstart.

Best regards,
Andreas
