Comment Re:No Need (Score 2) 282

I would say the same thing. The user can currently either choose a different "sub-distro" based on their primary flavour of choice, opt for a desktop/server specific spin, or just accept the current one distro to rule them all but just install the necessary packages for what they want approach. There really shouldn't be any need to split a Linux distro (or BSD distro for that matter) in two for this (and why stop there, why not a phone/tablet optimised version, or one for embedded devices...?) - just provide a specific spin for desktop that includes a selection of GUIs and another for servers that includes a broader selection of alternative server daemons and maybe a simple GUI for those that really need it. Apply some task specific optimizations to the default configuration files for bonus points and off we go.

Where, exactly, do I state that I am putting a GUI on a server? Perhaps you got confused when I mentioned Gnome requiring SystemD as an example of how applications making SystemD a dependency was forcing distros into a Hobson's Choice of either adopting SystemD whether they want to or not, or going through a lot of pain to replace it with an alternative when it breaks major dependencies like Gnome? RHEL, like many distros, includes Gnome - but how many of those distros have adopted SystemD mostly as a result of this, not because it is better or worse than the alternatives?

Note also that I point out that the dependencies work in *both* directions; as antientropic points out Gnome requiring SystemD is absolutely an issue with the Gnome team and nothing to do with SystemD, but it does have implications in that it helps build a mess of inter-dependencies that is making it increasingly hard to strip systems down to the minimum. RHEL's insistance on NetworkManager by default, with all the baggage that brings, doesn't inspire confidence either, as this is apparently one of the next daemon in SystemD's sights - maybe SystemD can improve it, but I'm not holding my breath.

Anyway, regardless of that, we've made our choice and moved to BSD; SystemD played a significant part in that, but it definitely wasn't the only factor, as I noted in my OP. ?

Improving the qualities of robusta or the hardiness of arabica, either works for me. I love the smell and taste of a well prepared coffee, but the increasing use of robusta has started to mess with my digestive system for some reason (I suspect the part that makes robusta taste bitter) making me feel like I've drunk acid. Adding sugar or salt (depending on the chain) helps a bit, but the result has been to pretty much stop me from buying coffee to drink from the usual high-street chains that are all we available here, and my attempts to offer feedback in the form of suggesting a "premium" high-arabica based brew don't seem to be getting very far.

I have three main issues with SystemD that might help you understand where some of us are coming from:

1. It effectively works as a monolithic replacement for several daemons, contra to core UNIX design tenets, and even though some of those sub-daemons can be swapped out with an alternative, often that works by running the second daemon in parallel - you can't actually disable the SystemD equivalent, let alone remove it altogether. This makes troubleshooting much more complicated when something goes wrong, especially if you have booted a system from a recovery disk to troubleshoot after a crash, compromise, or whatever and can no longer directly access several of the key sources of information necessary to do that.

2. Because of the growing number of packages that depend on SystemD, and vice-versa, it's creating a huge mess of package inter-dependencies that mean that it's getting almost impossible to build a stripped down and hardened server. Ballmer might have been right with his "Cancer" comment, he just wasn't specific enough: Gnome requires SystemD, $distro wants to bundle Gnome, therefore $distro adopts SystemD - and forces the default install of all the other package dependencies that go with it, thereby increasing the attack surface of the system. So much for hardening systems by removing all superflous code, huh?

3. All that cruft seems to be bogging the system down. We are currently migrating a large number (much larger than planned after initial results) of systems from RHEL to BSD - a decision taken due to general unhappiness with RHEL6, but SystemD pushed us towards BSD rather than another Linux distro - and in some cases are seeing throughput gains of greater than 10% on what should be equivalent Linux and BSD server builds. The re-learning curve wasn't as steep as we expected, general system stability seems to be better too, and BSD's security reputation goes without saying.

That said assuming that it "just works" a SystemD based desktop with everything from a desktop application down to the kernel talking through the same set of core services does sound like a nice idea. The problem is that most of us are not actually running Linux desktops; we're running servers and would just like the OS to mostly get the hell out of the way so we can get on with running whatever server daemons we are using. If SystemD were better architected - say a core PID1 init replacement, then a bunch of optional packages I don't even need to install if I want to use an alternative or not bother with at all, plus a massive clean up of the dependency hell that it has introduced - then I'd be a lot happier with it, but as it stands I just can't see including it on a hardened Internet facing server as being a remotely sane thing to do.

there are always people in third world countries who will do the same work as you for peanuts.

I remember spending hours untangling Bangalore Spaghetti Code. One application used a 2,000 character url string that passed the administrator user name and password in plain text. Cheaper does not mean better. People over there can work for peanuts because they live in cardboard ghettos. Maybe we want our people to have indoor sanitation, running water and electricity.

Maybe we should be considering trade barriers instead of feeling like we need to compete with starvation wages in every third world hell hole on the planet.

All our hopes and dreams revolving around deflecting asteroids and comets all hinge on being able to detect them far enough out to make an intercept. Makes me think we should really reconsider the priority we put on manned space missions, particularly generational missions. Otherwise we stand a good chance of getting snuffed out as a species if we hang around here long enough. Asteroids and comets are not even the most dangerous threats we face.

Attackers have used the Linux vulnerabilities on unmaintained servers to gain access, escalate privileges to allow remote control of the machine

Holy misleading headline, Batman! Any server that's not maintained is vulnerable, how is this news other than it's a Linux server botnet? OMG unpatched servers are vulnerable to hackers!

Well, the like-for-like retaliation from Ukraine won't happen. One of the terms of Ukraine's independance was that they give up the nukes they had left over from the break up of the USSR, but their supposed pay back from that would be protection from NATO if Russia were to invade. Now that a full scale invasion of Eastern Ukraine is clearly underway that comment was almost certainly aimed at NATO in an attempt to give them pause while the Russians consolidate their position and get dug-in.

At this point in time, with almost no response by NATO/the West other than some obviously ineffectual sanctions, my money is on Russia successfully annexing enough of Eastern Ukraine and the Crimea (albeit as an "independant" state with its capital in Donetsk or Sevastopol) that it can resupply the Crimea via land from mainland Russia.

Likewise. In the process of migrating a considerable proportion of a large RHEL estate over to BSD here. A general lack of satisfaction with RHEL6 started our look at alternatives - including other Linux distros - but SystemD was our deciding factor in the making the slightly more drastic leap from Linux to BSD. Despite the dream of Linux on the Desktop, most of us are actually running Linux on servers with (hopefully) competent personnel, so we don't really need some cuddly desktop OS that needs to pander to the lowest level of luser or the additional cruft and abstraction layers that brings, let alone the mess of package dependencies that seems to be afflicting Linux at present. In some cases we're seeing significant perfomance gains for what, in theory, should be the same basic set of code so for us it's more performance for less cost, and possibly an interesting call with our RHEL rep when the first tranche of RHEL licenses come up a renewal we are not going to need...

They have the vision and agility that NASA lost in the sixties.

I get smacked down here for suggesting that NASA is no longer the best agency for moving the space program forward. SpaceX soft-landed two boosters in the ocean and are ready for a land trial. They did that in their spare time. It would have taken NASA 10 years and $20 billion dollars to replicate that achievement. NASA also relies on contractors with obscene overhead rates.

SpaceX is living proof that NASA wastes billions.

Hmm, the plot thickens. I suspected it might just be a regional office based in Russia covering a large area of Eastern Europe that happens to include both Russia and The Ukraine that just happens to be located in Russia, which would have been a fairly sensible choice given that it has a both a larger on-line population and better technology infrastructure. That however does not appear to be the case at all. A quick search on Google shows that FB has been looking into opening a Russian office since early 2010, well before the conflict started, but while some of the stories from 2010 talk about it in the past tense, there is speculation in the future tense about it happening from 2012, and a map of FB offices around the world shows nothing in Russia. My guess is when they say "office", they really mean "department" or "desk", and it's actually most likely based either in the EU or the US.

That would be why I wrote "Ukrainians believe", but given the obvious bias shown by certain elements of the media on both sides of the conflict I don't think it much of a stretch that this could actually be happening. My point though was more about the general problem here in that most tend to be local enough to fall within the territory of the same regional office for a given company, and that office is within a country with a stake in the conflict, let alone one that has a track record for having poor freedom of the press, then accusations like this are probably inevitable. Now that the issue has been highlighted, we can only hope that FB et al think about how they might deal with such potential censorship in the future.
