We are surely aware about the criticism towards systemd as project. But this article should not only be focussed onto that and be therefore more oriented towards our reasoning for a system beyond using only bloated packages and frameworks. So we could now list for sure many reasons why we stay critical towards the adaption for systemd as basic init-framework, but we want to provide a complete picture.

Obarun compromises neither principles nor finctionality!

I feel like I have found a real hidden gem with Obarun.

I'm not a huge fan of SystemD, not because it's slow or anything, mostly ideological reasons. Plus I find Distributions that choose no to use it make other choices I like, such as being more minimalistic.

I went to through great efforts trying to remove SystemD completely from Gentoo (as you may be aware, it uses elogind and quite a bit of SystemD code even when using OpenEC as init). I got it done, sure, but at the cost ofba great deal of functionality. No elogind, no steam or firefox for you!

So down the rabbit hole, finding out most supposedly systemd free distros use great quantities of SystemD code. Very disappointing, why bother avoiding SystemD if you aren't going to follow through?

I find a lot of Distros that go the extra mile, but seems very difficult may be accused of being “memes” such as Kiss linux and whatnot. They look quite fun, but i need something less alien.

I stumble upon Obarun. The Arch base is comforting since I know Arch well, and s6 is intriguing. No SystemD nonsense whatsoever! I try it instantly! Some growing pains, s6 is pretty tricky compared to others.

22nd June 2018: Renaming Network Interfaces.</h3> <div class=“col-lg-10 col-lg-offset-1 text-left”> <p> As announced in the systemd mailing list, <a href=“https://lwn.net/Articles/758128/” target=“_blank” rel=“nofollow”>version 239 of systemd will name network interfaces differently than in previous versions</a>.</p> <p>Because breaking the name of my network adapter is exactly what I was asking for.</p> <p>There are a whole set of other changes in the same announcement which should make it clear to any sane person contemplating switching over to this system that it is not yet ready for production use. The definitions of blacklist/whitelist have swapped over; a hibernate update notes that “swap files should work for hibernation now.” - because it's absolutely fine to “support” hibernation for years, for 239 releases, without hibernation actually, well, working

<div class=“row” id=“dynamicusers”><h3>Dynamic Users</h3><div class=“col-lg-10 col-lg-offset-1 text-left”> <p>Dynamic Users is a feature added between v232 and v235 of systemd. There's a <a target=“_blank” rel=“nofollow” href=“http://0pointer.net/blog/dynamic-users-with-systemd.html”</a>blog post by Poettering here</a>.</p> <p>What is a Dynamic User, you ask?</p> <p>Well, it's a system account which is created when the service starts, and is deleted, along with all the files owned by that user, when it stops. And yeah, that's about as stupid and dangerous as you might imagine it to be. It claims that it avoids the “problem” (have you ever encountered this problem?) with the numerical limit on available UIDs and GIDs, yet it also allows for persistent directories - you know, just in case you wanted your data to still be there after you've restarted the service! (some people are *so* fussy about actually *keeping* their data, I don't know!).</p> <p>But it keeps them hidden under “chmod 0700” root-owned directories. Then they realised that if you start the service up again, and another process has taken your previous UID, then they'll have to do a recursive “chown -R” on your data, so you'll just have to wait for that to complete before you can start the task of actually starting up your application. Heaven forbid it'd be a large amount of data, or on a slow, or read-only, or remote media such as NFS.</p> <p>Given systemd's history in terms of security and protection of user data (that is, the designers simply don't care about such things), it will only be a matter of time (<B>the blog post above was 6/10/17; this rant was written on 17/10/17; I'll try to remember to update this piece when I hear of the first example of inadvertent data loss or exposure caused by systemd as soon as I hear of it</b>) until this implementation loses somebody their data. That is, if anybody is stupid enough to make use of this “feature” in the first place. Which does seem unlikely, since it's solving a problem that nobody has ever reported. Ever.</p>

<p><a target=“_blank” href=“https://cve.mitre.org/cgi-bin/cvename.cgi?name=2017-15908”>CVE 2017-15908</a> has the full details, and you can read a bit more in plain-English <a target=“_blank” rel=“nofollow” href=“https://usn.ubuntu.com/usn/usn-3466-1/”>from Ubuntu</a>, but in a nutshell: a given DNS response (so far, I believe, the details have not been made public) will cause systemd to hang entirely. So a total Denial of Service (DoS) attack on your ability to manage your system.</p> <p>Wow - nobody ever warned that there was a massive danger inherent in putting so much arbitrary code into

, did they?</p> <p>Oh, wait. They did. Yes. Absolutely everybody did warn them about this huge, monolithic, unwieldly

PID 1

process taking control of so may existing subsystems, with the potential for new bugs in any one of them to affect the stability of the entire system. Many times. We did that. But systemd rolled on anyway. And broke a lot of systems for a lot of people.

Yes it's true that some tools may need to write to it but those tools are not needed for the general running of a system. efivars should not even be mounted as read-only by default. Those tools that need to write to efivars will generally only be invoked by a system administrator. A competent sysadmin will know how to mount efivars with read/write permissions when they need to to use those tools. The only reason to mount efivars by default is for convenience. This is by no means a good reason. From a security perspective, mounting efivars by default should be strongly discouraged as it breaks the [https://en.wikipedia.org/wiki/Principle_of_least_privilege principle of least privilege]. Lennart goes on to state that [https://github.com/systemd/systemd/issues/2402#issuecomment-177907110 systemd needs to write EFI variables]. This demonstrates yet another example of scope creep and thus poor design. * http://anonscm.debian.org/cgit/pkg-systemd/systemd.git/commit/?h=ubuntu&id=28640752854 * https://bugzilla.redhat.com/show_bug.cgi?id=1170765 * https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=784720 * https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=825394 “Now you can no longer expect a long running background processes to continue after logging out.

* [http://lists.freedesktop.org/archives/systemd-devel/2015-February/028514.html Lead systemd developer doesn't understand RAID or checksum] * [https://github.com/systemd/systemd/issues/825#issuecomment-127917622 Lead systemd developer doesn't understand su, expects it to do something else and then labels it a “broken concept”] - su isn't supposed to inherit cgroups or audit, those concepts are relatively new and arrived well after the creation of su. TTYs were originally physical devices so of course su is supposed “inherit” the same device otherwise it would be truly broken. Pseudo TTYs emulate real TTYs so their behaviour is obviously expected to be identical. su really is just a simple mechanism that calls setuid(2) in order to switch to another user. If he needs to write a new utility to handle scenarios that su was never designed to handle, no problem, but to label it as a “broken concept” demonstrates a lack of understanding of what su actually is.

maybe use already installed sync plugin to pull resources from devuan wiki

As systemd doesn't follow our Social Contract, we have decided to remove it and use OpenRC as our default init system. The decision means that the Stable v0.1 will be the first and the last version supporting systemd.

To ease the transition, systemd support will remain in the stable repositories for the time being, while we are removing it in the Testing version and creating our OpenRC migration guide. As of Stable v0.2 release, systemd support will be completely removed without further notice.
