Well I did test that with my high-end setup (Intel Core i7 4790 + Asus Z97 Sabertooth + Samsung 850 Pro SSD) using CPU integrated GPU (Intel HD 4600). 1. If I only install systemd-sysv (thus upstart, upstart-bin and ureadahead are removed) and not do the kernel line addition, the setup will not boot at all. It will stop early complaining having init issues. 2. If I then recover the setup by chrooting (live USB) and re-installing upstart and upstart-bin plus removing systemd-sysv), the setup boots OK. 3. If I then only add the kernel line: init=/lib/systemd/systemd, the setup boots well, using systemd. Note: systemd-sysv not installed. 4. Lastly I tested booting by reinstalling systemd-sysv and removing all this: upstart, upstart-bin, systemd-shim, cgmanager, libcgmanager0, ifupdown, libjson0. The setup boots well. Note: the kernel line addition in use. So, at least for me only installing systemd-sysv will break the setup. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to init-system-helpers in Ubuntu. https://bugs.launchpad.net/bugs/1357713 Title: Use essential "init" package to ensure that an init system is present Status in “ifupdown” package in Ubuntu: Invalid Status in “init-system-helpers” package in Ubuntu: Triaged Bug description: I'm using Ubuntu 14.10 dev with ifupdown 0.7.48.1ubuntu4 and upstart 1.13.1-0ubuntu3 and currently it is possible to remove ifupdown and upstart as they are not essential packages or any essential/manual package does depend on them.

Do you want to continue? [Y/n] n Abort. As I know Ubuntu wants to change from upstart to systemd in the future so removing upstart may be fine but I'm wondering why ifupdown can be removed (wouldn't this remove the ability to create a network connection?).
