Systemd is one of the stupid ideas. It flies in the face of
everything that makes sense in Unix or Linux, and incorporates some
of the most amazingly bad ideas Microsoft ever promulgated. A

tasks incorporated in a single process just because we can...
I really wish people would stop repeating this falsehood. systemd is
*not* a single process. It's a name for a collection of small
processes that *collectively* are called systemd. There's no single
point of failure that's significantly more problematic than pid 1 has
ever been.
Sorry, but I have to call "bull" on that. It absolutely is a single
process (/usr/lib/systemd/systemd). The fact it delegates its operations
does not make it "a collection of small processes" any more than, say,
xinetd is when it launches programs to handle incoming network
connections.
systemd and upstart are misguided attempts to speed up the boot process
by parallelizing the startups. The race conditions inherent in both are
simply atrocious. Reboots have been (and should continue to be) fairly
rare events. You can't convince me that there was any real need to
speed that up. I mean, the BIOS self tests often take longer than the
OS boot. Do they really think they're saving anyone any time with this?
IMHO, systemd is a really, REALLY moronic solution to a problem that
never existed. Having the developers force people to use it when it
is very clear that it is not wanted is arrogance in the highest sense.
At this point, I am going to ignore the remainder of this thread.
