Re: remedying deficiencies in system 5 init

Ansgar Burchardt:
Isn't that just a hack to work  around deficits in sysvinit?

No. You wouldn't have ended up with systemd, or even something necessarily resembling it. You would have ended up with what you HAVE ended up with, which is a lot of designs and implementations, based upon a lot of differing engineering choices, some of which bear almost no resemblance to systemd (simpleinit, jinit, minit, cinit, finit, initng, runit's runit and runsvdir, nosh's system-manager and service-manager, ...). The idea of doing better than System V init and System V rc didn't suddenly appear in the late 2000s, after all. (-:
