@SteveBellovin @mms correct on all points. every single claim that systemd proponents make to its benefit is already an existing tool or command or method which has existed in Unix and BSDs (and to a lesser extent in pre-systemd Linux distros).
having been professionally involved with all of the major non-windows OS's for over a decade longer than systemd has existed, I can assuredly say that far too many of those claims exist simply due to the claimants vast inexperience with operating system design and engineering. they don't even know, and seemingly don't care, that we never needed systemd, and the vast majority never wanted it.
it's no coincidence that systemd was forced into the Linux communities at the same time that MSFT stopped trying to crush it from beyond -- instead that was the very same era in which they began their assaults on open source via "embrace extend extinguish".
