The idea is that the "Priority: required" init package is always installed, which depends on systemd-sysv | upstart-sysv. upstart-bin is history, that's "upstart" now (and as you already found out, upstart- sysv now contains /sbin/init).
Any idea how "init" got missing on your system? ** Summary changed: - Essential files are missing + init package is missing -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to upstart in Ubuntu. https://bugs.launchpad.net/bugs/1436691 Title: init package is missing Status in init-system-helpers package in Ubuntu: Confirmed Status in upstart package in Ubuntu: Invalid Bug description: I'm using Ubuntu 15.04 dev and upstart 1.13.2-0ubuntu10 doesn't contain files like /sbin/init anymore.
