just copying description from my duplicate bug as i think its probably / possibly useful
As seen in the failed systemd adt test at [1], installing 'upstart-bin' and then booting a system with 'init=/sbin/upstart' does not result in a fully functional system. The problem is that there are many upstart jobs provided by 'upstart' package that are essential to Ubuntu system boot. To recreate the problem, just launch a cloud-instance, or fresh install with systemd, then: sudo apt-get install upstart-bin set /etc/default/grub up appropriately and run 'update-grub' (adding 'init=/sbin/upstart to GRUB_CMDLINE_LINUX_DEFAULT). Alternatively, you can just edit /bo ot/grub/grub.cfg directly. reboot System will not completely come up. Installation of 'upstart' package *does* provide working boot, but conflicts and forces uninstallation of systemd-sysv, which is not desireable. For reference, there is discussion in ubuntu-release between infinity, didrocks, smoser and cjwatson on 2015-03-18 [2] and 2015-03-19 [3]. -- [1] https://jenkins.qa.ubuntu.com/job/vivid-adt-systemd/ARCH=amd64,label=adt/121/consoleFull [2] http://irclogs.ubuntu.com/2015/03/18/%23ubuntu-release.html [3] http://irclogs.ubuntu.com/2015/03/19/%23ubuntu-release.html -- 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/1422681 Title: split out upstart-sysv Status in upstart package in Ubuntu: Triaged Bug description: After switching to systemd permanently (apt get install systemd-sysv) and purging the now not needed "upstart" package, I tried to boot with the upstart fallback option in grub, just to find out it doesn't work. It looks like important init files are still in the "upstart" package instead of "upstart-bin" and should probably be moved there to keep the upstart fallback option working.
