This compat symlink has been around for many years, and documentation has long since been updated. Given the initrd tools are not going to add checks, I will just drop it now. Any user still setting manually init=/bin/systemd will just have to fix their local configuration after they notice the breakage. The systemd binary should most definitely not be in the default PATH, and that is more important than supporting hypothetical broken and unsupported local-only changes. -- Kind regards, Luca Boccassi
