> To solve the distribution and isolation problem, Linux engineers built a set of kernel primitives (namespaces, cgroups, seccomp) and then, in a very Linux fashion, built an entire ecosystem of abstractions on top to “simplify” things: [...] Somehow we ended up with an overengineered mess of leaky abstractions
Not sure I like the value judgement here. I think it's more of a consequence of Linux' success. I am convinced that if it was reversed (Linux was niche and *BSD the norm), then a ton of abstractions would come, and the average user would "use an overengineered mess" because they don't know better (or don't care or don't have a need to care).
Not that I like it when people ship their binary in a 6G docker image. But I don't think it's fair to put that on "those Linux engineers".

I don't think it's necessarily true, compare the BSD utils to the GNU utils and the style difference is very visible.
On the other hand, I don't think the comparison between jails and docker is fair. What made Docker popular is the reusability of the containers, certainty not the sandboxing which in the early days was very leaky.
NooneAtAll3•Feb 22, 2026
what do you mean by reusability?
maxloh•Feb 22, 2026
For example, you can build a Python image, and reuse it on every Python apps you have.

Well, what style difference exactly? GNU utils tend to be more verbose. Other than that, what is the difference in style?
jacquesm•Feb 22, 2026
I don't agree with that. FreeBSD has more of an engineering than a hacking mentality and it shows in the various architectural choices.
And containers really are a VM-light, so you might as well use the real thing, in fact, VMWare for a long time thought that their images would be a container like thing and many larger installations used them as such.

I ran a whole company on top of FreeBSD back in the day (2005 ish). It was great, and ran all my personal pcs the same way (hell, refusing to install windows to try out this bitcoin idea is even now a good idea).
But somehow Linux still took over my personal and professional life.
Going back seems nice but there need to be a compelling reason -docker is fine, the costs don’t add up any more. I do t have a real logical argument beyond that.
dijit•Feb 22, 2026
Yeah, I have a similar situation; FreeBSD is a great operating system, but the sheer amount of investment in Linux makes all the warts semi-tolerable.
I'm sure some people have a sunk-cost feeling with Linux and will get defensive of this, but ironically this was exactly the argument I had heard 20 years ago - and I was defensive about it myself then.. This has only become more true though.
It's really hard to argue against Linux when even architecturally poor decisions are papered over by sheer force of will and investment; so in a day-to-day context Linux is often the happy path even though the UX of FreeBSD is more consistent over time.

Windows developers (like sysadmins) are of two kinds in my experience.
People who don't understand shit about how the system behaves and are comfortable with that. "I install a package, I hit the button, it works"
.. and
People who understand very deeply how computers work, and genuinely enjoy features of the NT Kernel, like IOCP and the performance counters they offer to userland.
What's weird to me is that the competence is bimodal; you're either in the first camp or the second. With Linux (+BSD/Solaris etc;) it's a lot more of a spectrum.

anthk•Feb 22, 2026
Unix is easier to understand than the NT mess and everything it's in the open and documented, so you can achieve a good level of knowledge in the middle. OTOH in order to understand NT deeply you must be a reverse engineer. Also, on the other side, crazy experts under Wine (both ways, Unix and NT) OpenBSD and 9front do exist on par of these NT wizards. It just happen with Unix/9f you climb an almost flat slope (more in the second) due to the crazy simple design, while with NT the knowledge it's damn expensive to earn.
With 9front you OFC need expertise on par of NT but without far less efforth. The books (9intro), the papers, CSP for concurrency... it's all there, there's no magic, you don't need ollyDBG or an NT object explorer to understand OLE and COM for instance.
RE 9front? Maybe on issues while debugging, because the rest it's at /sys/src, and if something happens you just point Acid under Acme to go straight to the offending source line. The man pages cover everything. Drivers are 200x smaller and more understandable than both NT and Unix.
Meanwhile to do that under NT you must almost be able to design an ISA by yourself and some trivial compiler/interpreter/OS for it, because there's no open code for anything. And no, Wine is not a reference, but a reimplementation.

In the early years after 2000, FreeBSD 4 had a much better performance and reliability in any networking or storage applications in comparison with the contemporaneous Linux and Windows XP/Windows 2000.
However, in 2003 Intel introduced CPUs with SMT and in 2005 AMD introduced multi-core CPUs.
These multi-threaded and/or multi-core CPUs quickly replaced the single-threaded CPUs, especially in servers, where the FreeBSD stronghold was.
FreeBSD 4 could not handle multiple threads. In the following years Linux and Windows have been developed immediately to take advantage of multiple threads and cores, while FreeBSD has required many years for this, a time during it has become much less used than before, because new users were choosing Linux and some of the old users were also switching to Linux for their new computers that were not supported by FreeBSD.
Eventually FreeBSD has become decent again from the PoV of performance, but it has never been again in a top position and it lacks native device drivers for many of the hardware devices that are supported by Linux, due to much fewer developers able to do the necessary reverse engineering work or the porting work for the case when some company provides Linux device drivers for their hardware.
For the last 3 decades, I have been using continuously both FreeBSD and Linux. I use Linux on my desktop PCs and laptops, and in some computational servers where I need software support not available for FreeBSD, e.g. NVIDIA CUDA (NVIDIA provides FreeBSD device drivers for graphic applications, but not CUDA). I continue to use FreeBSD for many servers that implement various kinds of networking or storage functions, due to exceptional reliability and simplicity of management.

The jails vs containers framing is interesting but I think it misses why Docker actually won. It wasn't the isolation tech. It was the ecosystem: Dockerfiles as executable documentation, a public registry, and compose for local dev. You could pull an image and have something running in 30 seconds without understanding anything about cgroups or namespaces.
FreeBSD jails were technically solid years before Docker existed, but the onboarding story was rough. You needed to understand the FreeBSD base system first. Docker let you skip all of that.
That said, I've been seeing more people question the container stack complexity recently. Especially for smaller deployments where a jail or even a plain VM with good config management would be simpler and more debuggable. The pendulum might be swinging back a bit for certain use cases.

chuckadams•Feb 22, 2026
Docker's client/server design also allowed for things like Docker Desktop, which made the integration seamless with non-linux systems. Jails have nothing like that, so the only system that will ever run jails is FreeBSD. Also, I'm not up to speed enough to know, but do jails even have a concept of container images?
I'm using either Docker Compose or Docker Swarm without Kubernetes, and there's not that much of it, to be honest. My "ingress" is just an Apache2 container that's bound to 80/443 and my storage is either volumes or bind mounts, with no need for more complexity there.

It was the ecosystem: Dockerfiles as executable documentation, a public registry, and compose for local dev.

So where's Jailsfiles? Where's Jail Hub (maybe naming needs a bit of work)? Where's Jail Desktop or Jail Compose or Jail Swarm or Jailbernetes?
It feels like either the people behind the various BSDs don't care much for what allowed Docker to win, or they're unable to compete with it, which is a shame, because it'd probably be somewhere between a single and double digit percent userbase growth if they decided to do it and got it right. They already have some of the foundational tech, so why not the UX and the rest of it?

I do follow the news cycle and if I’m hearing about a software package in it, something is wrong with the people making the software and I don’t trust them. Software is an engineering discussion or at least it’s supposed to be. Here’s my community guidelines: everyone be nice and respectful engage in good faith and focus on the math. Being social is fine so long that it doesn’t become a diversion from the engineering discussion. We’re talking about code not a philosophical treatise. There are civil ways to settle disagreements. I’m so sick to death of the politics.

Uh... Xorg is packaged by FreeBSD too...
Really the whole theme that (from the article) "FreeBSD ships as a complete, coherent OS" is belied by this kind of nonsense. No, it's not. Or, sure, it is, but in exactly the same way that Debian or whatever is. It's a big soup of some local software and a huge ton of upstream dependencies curated for shipment together. Just like a Linux distro.
And, obviously, almost all those upstream dependences are exactly the same. Yet somehow the BSD folks think there's some magic to the ports stuff that the Linux folks don't understand. Well, there isn't. And honestly to the extent there's a delta in packaging sophistication, the Linux folks tend to be ahead (c.f. Nix, for example).

What specifically are you trying to cite here? Which package can I install on Debian or Fedora or whatever that "bricks the system"? Genuinely curious to know.
rednb•Feb 22, 2026
I was referring to the need to be careful to not modify/update packages also used by the base system. Since all packages are treated the same on Linux, you often can't tell which package can put you in trouble if you update it along with the dependencies it drags with it.
This kind of problem happens frequently when users add repositories such as Packman on Linux providing dependencies versions different from the ones used by the base system of the distro.
Experienced people know how to avoid these mistakes, but this whole class of problem does not exist on FreeBSD.
user3939382•Feb 22, 2026
> a huge ton of upstream dependencies
I think you missed the point in my original comment. I explained I moved my platform with all dependencies and had 1 bug which was actually a silent bug in Linux.
In other words, it works. Your particular stack might have a different snag profile but if I can move my giant complex app there, yours is worth a shot.
FreeBSD is more complete than you make out. They also have hard working ports maintainers.
rednb•Feb 22, 2026
Done the same since 2018 circa, never looked back.
For a while even used it on the desktop, but was too much trouble due to specific tools we need that weren't supported properly. so we're using Linux on the desktop.
FreeBSD is stable, lightweight, gets out of the way, and without drama.
jmclnx•Feb 22, 2026
>but they don't have a native answer to shipping
I am not quite sure what this means. I had a jail a few years ago and I remember there was a utility to "back" the jail up so you could put it on another system. Are there constraints with that utility. It seemed to work, maybe I am forgetting something ?
In any case I still think Jails are much better than the things Linux has. To me, it is creating a jail that is more difficult. There were ports that made it easier, I used one of them, but that port was abandoned at some point. I think it was "ezjail".
> FreeBSD is worth a brief aside here, because it differs from Linux in a fundamental way. Linux is a kernel. What most people call "Linux" is actually that kernel combined with a GNU userland, a package ecosystem, and a set of choices that vary from distro to distro — Ubuntu, Fedora, and Arch are all running the same kernel but are meaningfully different systems underneath.
It is not incorrect but ... do people really care about that distinction?
Because in most situations I know of, when people refer to Linux, they almost never refer to the linux kernel. They refer to the whole operating system stack, which is typically put down via a distribution. So, Fedora, Gentoo, Arch, and so forth, are all "kind of" Linux. Barely anyone refers to the linux kernel if you look at all the discussions on the world wide web.
> FreeBSD ships as a complete, coherent OS
The BSDs often promote that aka "Linux is chaos, we are coherent and consistent operating system following intelligent design". Well ... this is the rise of worse is better, repeated: https://dreamsongs.com/WorseIsBetter.html
It is a great analogy that works on so many levels. Broken down to Linux versus the BSDs, I think 500 out of 500 top supercomputers running Linux kind of show which philosophy is better. The one that works better. That does not mean the BSDs are useless, but I am getting tired of the promo used by the BSD as "we are order, Linux is chaos". I compare this more to Lego building blocks. With Linux there is a stronger focus on having building blocks available. You can build up things. You have projects such as LFS/BLFS (Linux from scratch). The BSDs do not have something comparable. Which operating system is the better tinker OS? Which community created git? (Ok ok that was Linus so not really a community per se, but it originated from Linux and perhaps that was not an accident either.)
> FreeBSD pioneered the practical implementation of what we now call containers.
Ok great. Many modern programming languages learned from older languages; many of these older languages are dead now. You need to keep on innovating. Why is BSD so dead set on the past?
> FreeBSD reached that third stage in 2000. Linux wouldn't get there until 2008 with LXC.
Dumdedum ... it kind of sounds as if the FreeBSD guys are sad that Linux went on to dominate. It reminds me of NetBSD aka "we work on every toaster in the world". Then suddenly on a mailing list many years ago "wait a moment ... Linux now works on more toasters than we do". The BSDs don't seem to understand how momentum can be dominating.
> Technical superiority doesn't win ecosystem wars. Linux won through a combination of fast decisions, the viral GPL licence, and strong enterprise backing from Red Hat and IBM. Then Google, Facebook, and Amazon happened — hungry for datacenters, developing tools to manage growing infrastructure at scale. They set the direction for the entire industry.
Ok that flat out is incorrect. First - GPL worked well for the linux kernel, that is true. But the ecosystem includes many BSD-licences programs too, on Linux. So that explanation fails already here. LLVM has Apache License 2.0 which I kind of feel is a mix between GPL and BSD (not quite true but this is how I remember it).
Then the claim is Linux won because of Red Hat. I actually find Red Hat annoying and I am glad to not depend on it. Linux is way bigger than Red Hat. IBM? I don't see what IBM did for Linux really. So that explanation also does not work.
Google, Facebook, and Amazon - well, they profited from Linux. They didn't really ENABLE Linux. They would not have used Linux if Linux would have been useless. So that part came afterwards.
So none of those explanations really work well here.
> Linux rapidly went from "the free OS for people who can't afford commercial licences" to "the only acceptable OS for servers".
That is true but not for the claims made, e. g. "because of Google". The more important question is: why did the BSDs fail?
> To solve the distribution and isolation problem, Linux engineers built a set of kernel primitives (namespaces, cgroups, seccomp) and then, in a very Linux fashion, built an entire ecosystem of abstractions on top to “simplify” things

Wait a moment - he cites Docker. That's owned by a private company. What does this have to do with Linux? If company xyz does something based on FreeBSD, we would then say company xyz is responsible for FreeBSD failing or not failing? How does that work?
> And this complexity has quietly reshaped how the industry thinks about deploying software. Today, if you want to run an application in a larger system, the implicit assumption is that you containerise it with Docker and orchestrate it with Kubernetes.
Personally I find all this abstraction crap. With all their failures, though, things such as docker kind of present a "download this one file, then it will work fine". And that is kind of true. I saw that in in-campus use for life science faculty clusters and what not. It simplifies things for the admin there. People give a similar rationale for systemd. Personally I don't think systemd should exist, but there are people who benefit from it - that simply is a factual statement.
All in all this is a very strange point of view from FreeBSD folks. At the least the NetBSD folks back then on the mailing list acknowledged the situation and then tried to find alternative strategies and in some ways succeeded (although I am not sure whether NetBSD right now runs on more toasters than Linux does - anyone has updated statistics for that?).

I frequently see freeBSD jails as a highlighted feature, lauding their simplicity and ease of use. While I do admire them, there are benefits to the container approach used commonly on linux. (and maybe soon freebsd will better support OCI).
First it's important to clarify "containers" are not an abstraction in the linux kernel. Containers are really an illusion achieved by use of a combination of user/pid/networking namespaces, bind mounts, and process isolation primitives through a userspace application(s) (podman/docker + a container runtime).
OCI container tooling is much easier to use, and follows the "cattle not pets" philosophy, and when you're deploying on multiple systems, and want easy updates, reproducibility, and mature tooling, you use OCI containers, not LXC or freebsd jails. FreeBSD jails can't hold a candle to the ease of use and developer experience OCI tooling offers.
> To solve the distribution and isolation problem, Linux engineers built a set of kernel primitives (namespaces, cgroups, seccomp) and then, in a very Linux fashion, built an entire ecosystem of abstractions on top to “simplify” things.
This was an intentional design decision, and not a bad one! cgroups, namespaces, and seccomp are used extensively outside of the container abstraction. (See flatpak, systemd resource slices, firejail). By not tieing process isolation to the container abstraction, we can let non-container applications benefit from them. We also get a wide breadth of container runtime choices.
Melatonic•Feb 22, 2026
Jails have been around a long time in comparison
I still see FreeBSD as being great for things like networking devices and storage controllers. You can apply a lot of the "cattle vs pets" design one level above that using VMs and orchestration tools.

Just like a Linux distro.
And, obviously, almost all those upstream dependences are exactly the same. Yet somehow the BSD folks think there's some magic to the ports stuff that the Linux folks don't understand. Well, there isn't. And honestly to the extent there's a delta in packaging sophistication, the Linux folks tend to be ahead (c.f. Nix, for example).
What specifically are you trying to cite here? Which package can I install on Debian or Fedora or whatever that "bricks the system"? Genuinely curious to know.
This kind of problem happens frequently when users add repositories such as Packman on Linux providing dependencies versions different from the ones used by the base system of the distro.
Experienced people know how to avoid these mistakes, but this whole class of problem does not exist on FreeBSD.
I think you missed the point in my original comment. I explained I moved my platform with all dependencies and had 1 bug which was actually a silent bug in Linux.
In other words, it works. Your particular stack might have a different snag profile but if I can move my giant complex app there, yours is worth a shot.
FreeBSD is more complete than you make out. They also have hard working ports maintainers.
For a while even used it on the desktop, but was too much trouble due to specific tools we need that weren't supported properly. so we're using Linux on the desktop.
FreeBSD is stable, lightweight, gets out of the way, and without drama.
I am not quite sure what this means. I had a jail a few years ago and I remember there was a utility to "back" the jail up so you could put it on another system. Are there constraints with that utility. It seemed to work, maybe I am forgetting something ?
In any case I still think Jails are much better than the things Linux has. To me, it is creating a jail that is more difficult. There were ports that made it easier, I used one of them, but that port was abandoned at some point. I think it was "ezjail".

It is not incorrect but ... do people really care about that distinction?
Because in most situations I know of, when people refer to Linux, they almost never refer to the linux kernel. They refer to the whole operating system stack, which is typically put down via a distribution. So, Fedora, Gentoo, Arch, and so forth, are all "kind of" Linux. Barely anyone refers to the linux kernel if you look at all the discussions on the world wide web.
> FreeBSD ships as a complete, coherent OS
The BSDs often promote that aka "Linux is chaos, we are coherent and consistent operating system following intelligent design". Well ... this is the rise of worse is better, repeated: https://dreamsongs.com/WorseIsBetter.html
It is a great analogy that works on so many levels. Broken down to Linux versus the BSDs, I think 500 out of 500 top supercomputers running Linux kind of show which philosophy is better. The one that works better. That does not mean the BSDs are useless, but I am getting tired of the promo used by the BSD as "we are order, Linux is chaos". I compare this more to Lego building blocks. With Linux there is a stronger focus on having building blocks available. You can build up things. You have projects such as LFS/BLFS (Linux from scratch). The BSDs do not have something comparable. Which operating system is the better tinker OS? Which community created git? (Ok ok that was Linus so not really a community per se, but it originated from Linux and perhaps that was not an accident either.)
> FreeBSD pioneered the practical implementation of what we now call containers.
Ok great. Many modern programming languages learned from older languages; many of these older languages are dead now. You need to keep on innovating. Why is BSD so dead set on the past?
> FreeBSD reached that third stage in 2000. Linux wouldn't get there until 2008 with LXC.
Dumdedum ... it kind of sounds as if the FreeBSD guys are sad that Linux went on to dominate. It reminds me of NetBSD aka "we work on every toaster in the world". Then suddenly on a mailing list many years ago "wait a moment ... Linux now works on more toasters than we do". The BSDs don't seem to understand how momentum can be dominating.
> Technical superiority doesn't win ecosystem wars. Linux won through a combination of fast decisions, the viral GPL licence, and strong enterprise backing from Red Hat and IBM. Then Google, Facebook, and Amazon happened — hungry for datacenters, developing tools to manage growing infrastructure at scale. They set the direction for the entire industry.
Ok that flat out is incorrect. First - GPL worked well for the linux kernel, that is true. But the ecosystem includes many BSD-licences programs too, on Linux. So that explanation fails already here. LLVM has Apache License 2.0 which I kind of feel is a mix between GPL and BSD (not quite true but this is how I remember it).
Then the claim is Linux won because of Red Hat. I actually find Red Hat annoying and I am glad to not depend on it. Linux is way bigger than Red Hat. IBM? I don't see what IBM did for Linux really. So that explanation also does not work.
Google, Facebook, and Amazon - well, they profited from Linux. They didn't really ENABLE Linux. They would not have used Linux if Linux would have been useless. So that part came afterwards.
So none of those explanations really work well here.
> Linux rapidly went from "the free OS for people who can't afford commercial licences" to "the only acceptable OS for servers".
That is true but not for the claims made, e. g. "because of Google". The more important question is: why did the BSDs fail?
> To solve the distribution and isolation problem, Linux engineers built a set of kernel primitives (namespaces, cgroups, seccomp) and then, in a very Linux fashion, built an entire ecosystem of abstractions on top to “simplify” things
No, that is also incorrect. cgroups are also very different to seccomp and the latter is even maintained independently: https://github.com/seccomp/libseccomp/releases
> Somehow we ended up with an overengineered mess of leaky abstractions for cloud-based, vendor-locked infrastructure.
Wait a moment - he cites Docker. That's owned by a private company. What does this have to do with Linux? If company xyz does something based on FreeBSD, we would then say company xyz is responsible for FreeBSD failing or not failing? How does that work?
> And this complexity has quietly reshaped how the industry thinks about deploying software. Today, if you want to run an application in a larger system, the implicit assumption is that you containerise it with Docker and orchestrate it with Kubernetes.
Personally I find all this abstraction crap. With all their failures, though, things such as docker kind of present a "download this one file, then it will work fine". And that is kind of true. I saw that in in-campus use for life science faculty clusters and what not. It simplifies things for the admin there. People give a similar rationale for systemd. Personally I don't think systemd should exist, but there are people who benefit from it - that simply is a factual statement.
All in all this is a very strange point of view from FreeBSD folks. At the least the NetBSD folks back then on the mailing list acknowledged the situation and then tried to find alternative strategies and in some ways succeeded (although I am not sure whether NetBSD right now runs on more toasters than Linux does - anyone has updated statistics for that?).
Or is it because it's what they're used to. I saw this argument elsewhere where the respondent went on to show that the users were Linux specialists and that's why Linux was used.
First it's important to clarify "containers" are not an abstraction in the linux kernel. Containers are really an illusion achieved by use of a combination of user/pid/networking namespaces, bind mounts, and process isolation primitives through a userspace application(s) (podman/docker + a container runtime).
OCI container tooling is much easier to use, and follows the "cattle not pets" philosophy, and when you're deploying on multiple systems, and want easy updates, reproducibility, and mature tooling, you use OCI containers, not LXC or freebsd jails. FreeBSD jails can't hold a candle to the ease of use and developer experience OCI tooling offers.
> To solve the distribution and isolation problem, Linux engineers built a set of kernel primitives (namespaces, cgroups, seccomp) and then, in a very Linux fashion, built an entire ecosystem of abstractions on top to “simplify” things.
This was an intentional design decision, and not a bad one! cgroups, namespaces, and seccomp are used extensively outside of the container abstraction. (See flatpak, systemd resource slices, firejail). By not tieing process isolation to the container abstraction, we can let non-container applications benefit from them. We also get a wide breadth of container runtime choices.
I still see FreeBSD as being great for things like networking devices and storage controllers. You can apply a lot of the "cattle vs pets" design one level above that using VMs and orchestration tools.
Spawning a linux container is much simpler and faster than spawning a freebsd jail.
I don’t know why i keep hearing about jails being better, they clearly aren’t.
OpenVZ and Linux vserver are older than LXC and were commonly used, though they required a patched kernel.
Is it really so necessary to put Vercel Security Checkpoint that apparently not working here?
