What systemd does is give a single consistent way of configuring the system. You want security nightmare, how about the 1000's of freaking shell scripts that call each other in a giant mass of spaghetti to configure a traditional Linux system.

With this, and the rest of your post, and with all respect: Do you know what you are actually talking about; or are your arguments based on a philosophical base of hearsay?

$ ls -l /lib/systemd/system | wc -l
52
makes it already some fifty files.

And how does one file look like?
$ cat sudo.service
[Unit]
Description=Provide limited super user privileges to specific users
[Service]
Type=oneshot
# \073 is ';' which needs to be part of the find parameters
ExecStart=/usr/bin/find /var/lib/sudo -exec /usr/bin/touch -d @0 '{}' \073
[Install]
WantedBy=multi-user.target

Oh wow! What a beauty, totally easy to understand and maintain!

How much worse is the old style:
$ cat sudo
#! /bin/sh
. /lib/lsb/init-functions
N=/etc/init.d/sudo
set -e
case "$1" in
    start)
                # make sure privileges don't persist across reboots
                if [ -d /var/lib/sudo ]
                then
                                find /var/lib/sudo -exec touch -d @0 '{}' \;
                fi ;;
    stop|reload|restart|force-reload|status) ;;
    *)
                echo "Usage: $N {start|stop|restart|force-reload|status}" >&2
                exit 1 ;;
esac
exit 0

Your comment is totally valid, though unexpected at an ID of close to 3 million.
Exactly true. That Poettering has not been bashed left and right, alas, has to make with our current times. In 2015, a number of companies are not satisfied with their own turf, and rather 'attract' customers from the other side of the wall. And those quite often have no good command of *nix, some not at all. But they like ubiquitous unreadable binary files and blobs, registries, and cherish the idea that a downtime is best rectified by filing a service request with the manufacturer, consulting some *-SuperSite, fiddling with GUI-elements (almost) exclusively, etc.
Sometimes I feel that the beauty of such a sysadmin is, that (s)he can confidently and honestly state: "You can't resolve many problems yourself, anyway". True. But, alas, not on *nix. With systemd, however, this great 'excuse' has made its entrance. Finally, we (they) have a great excuse for inactivity at system failure: "systemd got problem".

Anyway, I assume the various distros that are switching to systemd are doing it for a reason - and that reason isn't to make it work more like Windows. I assume it's to make it work - i.e. resume from suspend reliably, etc.

Oh my, we are talking servers here; respectively answering the question of the OP. And then 'resume from suspend' is only one thing, and that's OT.

Your low ID proves that you mean what you stated, I guess. My ID is much higher, though I think I've been in the business for a similar amount of time. And I can fully second what you wrote. Both passages.
But since I have no mod points, I can only second you here in writing. Especially I love the comparison to the Windows registry. Though systemd is not much different from that dreaded registry, alas.

When I was sysadmin, be it on Windows, *BSD or another *nix, my (personal) nightmare would be my incapacity of troubleshooting a problem by myself, and instead filing a support request. Therefore, Windows was the first platform I left. Because, if I can't locate and rectify the trouble due to my lack of knowledge, I hate myself; though I can live with it. However, if I can't locate and rectify the trouble by design of the manufacturer, I could throw myself into the dustbin. Because all my efforts to improve, study, experiment would be in vain by definition of the software providers. Be they in RedMond or RedHat.

This is 100% insightful. I have no mod points.
Systemd is great for me on the desktop; and yet not necessary. Systemd is a no-no on the reliable server (it isn't even 100% reliable on my desktops). I suffered from the Solaris SMF a decade ago.
As sysadmin, if my init scripts don't run, I could troubleshoot one by one (if ever I wanted, though I rarely had to), SMF didn't give me that privilege. And systemd wouldn't neither.

apt-get install OpenBSD

I wonder if I was to mod you up for insightful or funny.
But that aside, I wished it was as easy as that. Really. Theo is not going to like that, neither.
For the home router, at least, you are right with the lousy SMP support. I wished there was an OpenBSD equivalent for m0n0wall / pfsense. Installing OpenBSD is much too much for a small home router, e.g. on a Soekris box.

What misrepresentation?
I as ex-sysadmin kind of love systemd on my desktop; for the simplicity. From own experience I know that at times my desktops prop up some 'failed to start services - do you want to report - ...'-messages that are non-reproducible, occur rarely, and despite of digging into them never revealed actual problems. On the desktop they are nothing but an emotional disappointment about the state of FOSS.
One thing, however, is sure: I wouldn't for my life have trusted my servers to such a monolithic all-invading conglomerate of evolving software. If I were still sysadmin, and were sitting on Linux, I'd avoid systemd like the devil.

For your ID (low) you seem to be very modern; 4 GB is 'very small'? ;-)

To me, personally, I used floppyfw for years. Okay, that's Linux-based, though on 1.44 MB. Then I went over to BSD-based m0n0wall, the precursor of pfsense, and run it from a - much too large - 256 MB Flash.
While pfsense is out for me, due to it huge (okay, in my notation) demand on RAM. My Soekris 4801 has a mere 128 MB of it, which is more than enough for m0n0wall, though below the requirements of pfsense.

Since I can fully recommend m0n0wall, and used it with almost no intervention and no trouble at all (except of the initial setup which is somewhat ambiguous), I am confident that pfsense is doing fine as well.

I was hoping for the complete Lena. When the image popped up, in the 1970s, sure that the larger parts of the image were cut off for indecency.

Amazing.
An AC modded down for a crudely shortened summary, to a minus 1. Actually, no.
And the next poster at this moment in time, another AC, says 'nope'.
Has the mod (wo)man posted as AC to strengthen her statement?

While AC's comment wasn't really up to the article, the paper by Kadanoff does what parent is saying; and it is what re-normalization is about.
http://www.studiolo.org/Mona/M... and http://etd.lsu.edu/docs/availa...
are prior art. The former if you're more in arts, the second if you're more in physics/maths.
I don't want to say that there is not much in the paper, it is not my field. Common sense makes me wonder how much effort is necessary in the competitive academic world of our time to self-promote one's work on /.; or to get someone's friends to promote an otherwise not earth-shattering approach into the headlines.

But I can't help it.

Diesel is the better fuel, it results in a lower consumption, less dangerous. Buy a barrel and try to set fire to it, you'd be surprised! Try the same with petrol (oh, please don't!).
Consumption is lower, I mentioned it. In the refining process, it comes out as the 'lower quality', though.
Buy a modern diesel engine, and it neither stinks nor does it make more noise.

The whole thing is a sick publicity stunt by the former girl-friend of the French president.

I could agree on one single item where diesel is worse than petrol: that's the particles in the exhaust fumes. However, these are not dangerous at all to nature. It only so happens that they are seen at the origin of one or another cancer. But that's a problem mostly to us, the oxygen-breathing species. How can we dare to use significantly more oil, and waste mother nature's resources; produce more CO2; generate more heat, etc. for just one egotistic reason: prevent a number of lung cancers. A number that fades into oblivion compared to the numbers produced by the Marlboro Man and his followers, the pollution produced by capitalist enterprises around the world, including the 'communist' PRC.

Hi, its me again, it bugged me too much to let it slip. 2007, so, yes, bloody repeats and lousy editing. Dr. Google gives you a whole list at 'TGV speed'; for example this one: http://en.wikipedia.org/wiki/T...

Now don't come and tell me 'Maglev' was different. On the contrary, without rails, it ought to go even faster. Plus, Maglev uses by definition more energy. Nothing against the Japanese here, but this is no more than an academic achievement. What's the point of using a system that consumes more energy for a lesser speed?

Oh, and don't come to me with the reduction of noise by avoiding the noise of the rails on a track. This has been debunked in the early 1980, when it was shown that the rolling of wheels on rails actually is the main noise component, but only for low speeds, beyond 180 or 250 km/h it is the displacement of air that produces the higher noise components.

I can only take guesses why the Japanese still try: to avoid the almost completely stonewalled intellectual property around the technological leader, the TGV. German Rail had tried to do exactly that: work around the patents used for the French TGV, at the loss of more than 100 lives at Eschede. I'll surely leave out the gory and sad details of that, however. Promised!
