ZDNET’s key takeaways

  • RakuOS is a hybrid immutable/standard Linux distro
  • With RakuOS you get the best of both worlds with security and usability.
  • RakuOS can be downloaded and installed for free.

Immutable Linux is about as secure as an OS can get. By mounting certain directories as read-only, malicious code or bad actors cannot affect the data within. I could seriously place my full faith in immutable Linux and not worry about a thing.

Until I wanted to install an application using the distribution’s built-in package manager.

With immutable Linux distributions, software is typically installed via containers, such as Flatpak or Snap. Installation of apps is done this way because of the read-only nature of certain directories. Because of that, standard package managers cannot install the necessary files, so using the likes of apt, dnf, or pacman is a no-go.

Does that mean you’re limited to the apps you have available on an immutable distribution? Somewhat. Don’t get me wrong, the average user won’t feel as if they’re missing out on anything because Flathub and Snapcraft have tons of apps.

But when I’m using an immutable distribution, and I want to install something like Ollama, I’m out of luck if I want to ensure I’m using the latest version of the app (I currently run Ollama 0.30.7 on my Pop!_OS desktop). I’ve attempted to install Ollama via Flatpak, and although the command completes, the app is nowhere to be found. I’ve tried several times, but the end result is a failure. However, running the command sudo dnf install ollama works just fine; it shouldn’t, but it does.

Why should the DNF command fail? Because RakuOS is immutable, installing via DNF shouldn’t be possible. That’s where RakuOS says, nay, nay. How does RakuOS pull this off? According to the official site, “RakuOS uses a persistent overlay system mounted directly on /usr. Your base system is always pristine — but you can install any native package you want, and it survives every system update.”

With this hybrid system, you get:

  • An immutable base system with instant bootc rollback.
  • Native packages that automatically persist across updates.
  • Allows installation via dnf, dnf5, or the RakuOS Software Center.
  • A pristine system reset with a single command (more on that in a bit).
  • Flatpak for sandboxed apps (heightened security) and native packages for everything else.

In other words, you get the best of both worlds.

My experience with RakuOS

RakuOS

The RakuOS desktop might not be the most elegant desktop on the market, but it’s still pretty special.

Jack Wallen/ZDNET

The thing I appreciated the most about RakuOS is that, while it had all of the underpinnings of an immutable distribution, it still felt like a traditional Linux OS. The only difference was that instead of the KDE Plasma Discover app store, there was the RakuOS Software app store. The good news is that the RakuOS Software app looked and behaved similarly to that of Discover.

The RakuOS App Store is quite user-friendly.

With RakuOS, I was able to install all of the software I normally would use via a combination of Flatpak and DNF. If I wanted to install an app with the added security of isolation, I used Flatpak; otherwise, I dove into DNF.

As far as performance is concerned, RakuOS uses the CachyOS kernel, so it’s built for speed. No matter what I threw at the desktop, it didn’t bat an eye. Even running a hefty Ollama query (writing a Python GUI app) didn’t slow the machine down.

It’s hard to beat the CachyOS kernel.

Jack Wallen/ZDNET

That CachyOS kernel is something special, and the RakuOS devs were smart to include it.

But then, my curiosity got the best of me, and I decided to try the “pristine reset” option to see how well it worked. After installing several apps and saving some files/data to my home directory, I scoured the RakuOS website for any mention of the actual command used for this, but found nothing.

Given how RakuOS creates the overlay in /usr, I thought, “What happens if I simply remove everything in /usr? Couldn’t hurt, right? I am running RakuOS as a virtual machine, so if it does FUBAR the system, I can spin up another VM without much trouble. 

Ergo, I issued the command:

sudo rm -rf /usr/

That was a bit nerve-racking.

A quick restart to see what the results were, only to find the restart failed. I forced the VM off and then restarted. The boot process took considerably longer than I would have expected, but then, given that I’d nuked the /usr directory, I’m thinking maybe RakuOS had to rebuild it. 

Also: I tried a Linux distro that promises free, built-in AI – and things got weird

Maybe?

I waited, and waited, and waited. 

No dice.

Once more unto the breach with a reboot, and the same issue persisted. Time to reinstall. This time around, I remembered that RakuOS was based on OSTree, so the command was simple:

sudo rpm-ostree reset

Even someone who’s used a piece of technology for decades can get tripped up now and then.

The second time around, everything went well, and I wound up with a pristine OS (after installation, use, and resetting with the proper command).

My final thought on RakuOS is this: I’m impressed. This Linux distribution gives users the best of both worlds: immutability with the ability to use default package managers. Although installation takes a bit longer than I’m used to, the end result is very much worth the time invested. 

If you’re looking for an OS that is equal parts secure and user-friendly, give RakuOS a try. You can download an ISO for the KDE Plasma, GNOME, or COSMIC versions, create a bootable USB drive, and install it.

If you’re already running a Fedora Atomic-based distro, you can reset with:

sudo rpm-ostree reset

And then you can rebase to RakuOS with one of the following commands:

The Argentine markets took a beating last week, but US Treasury Secretary Scott Bessent has rushed to the rescue with a remarkable promise: America will provide what amounts to unlimited support to prop up Argentina. His declaration that “all options for stabilization are on the table” – including swap lines, direct currency purchases, and buying Argentine government debt – represents an extraordinary blank check.

But here’s the real kicker: Bessent claims Argentina is “systemically important” to the United States. This is financial fiction at its finest.

The Systemic Importance Fairy Tale

Let’s be brutally honest: Argentina poses zero systemic risk to the US financial system. US banks have minimal exposure to Argentine debt. Trade between the two countries is negligible in the context of the US economy. If Argentina defaulted tomorrow, would Bank of America collapse? Would JPMorgan need a bailout? Of course not.

The “systemically important” label is being stretched beyond recognition. If Argentina qualifies, then virtually every country in Latin America – including those the Trump administration just hit with massive tariffs – should qualify too.

This isn’t about systemic risk; it’s about political preferences dressed up as financial necessity.

The Moral Hazard Machine

By offering essentially unlimited support to Argentina, the US is creating a massive moral hazard problem.

The message to Milei’s government is clear: Don’t worry about the hard work of building political coalitions or passing sustainable reforms through parliament. Uncle Sam will catch you if you fall.

This is precisely the wrong incentive structure. Argentina has defaulted on its sovereign debt nine times since independence. Nine times!

The country’s political economy is fundamentally broken, cycling through periods of populist spending followed by crisis and austerity. US financial support doesn’t fix this cycle – it enables it.

The Real Threat to US Financial Stability

Here’s the irony: While Argentina poses no systemic risk to the US, this bailout policy might. Not directly through financial contagion, but through the precedent it sets.

If the US Treasury is willing to provide unlimited support to a serial defaulter like Argentina simply because its president is friendly with Trump and speaks the MAGA language, what’s to stop other countries from playing the same game? Elect a Trump-friendly president, make the right noises about being an ally, and wait for the bailout when things go south.

This transforms the US Treasury into a global lender of last resort – not for genuine systemic crises, but for politically favored regimes. That’s a commitment the US cannot afford, especially when federal debt is already approaching dangerous levels.

The Buenos Aires Reality Check

The timing of Bessent’s announcement is telling. It comes right after Milei’s party got hammered in regional elections in Buenos Aires. The political message from Argentine voters was clear (rightly or wrongly): Milei’s policies aren’t working, and he lacks popular support for his reforms.

Rather than forcing Milei to build political consensus and pursue genuine institutional reforms, the US bailout allows him to double down on rule by decree. This is not sustainable governance. It’s political theater subsidized by American taxpayers.

Where’s the “America First”?

This is where the contradictions become absurd. The Trump administration came to power promising “America First” – putting American workers and taxpayers first, being tough on countries that don’t pay their fair share, and ending the era of the US playing global policeman.

Yet here we are, with a Trump-appointed Treasury Secretary promising unlimited support to a country that has stiffed international creditors nine times. How exactly does bailing out Argentine bondholders put American workers first? How does propping up a foreign government that can’t even win local elections serve US interests?

The Unlimited Commitment Problem

Perhaps most troubling is the open-ended nature of Bessent’s commitment. “All options are on the table” with no conditions, no limits, no requirements for structural reform. This isn’t a rescue package – it’s a blank check.

What happens when Argentina needs another injection in six months? Another one in a year? At what point does the US Treasury say “enough”? And when that moment comes as it inevitably will won’t the withdrawal of support trigger an even bigger crisis?

The Alternative Nobody Wants to Discuss

Here’s what should happen: Argentina should be allowed to face the consequences of its political and economic choices.

Yes, this means potential default. Yes, this means economic hardship. But it also means the country would finally be forced to confront its fundamental problems rather than papering them over with foreign money.

The IMF learned this lesson the hard way after multiple failed bailouts. Now the US seems determined to repeat the same mistakes, but with even less conditionality and oversight.

Conclusion

This isn’t about whether one likes or dislikes Milei. It’s about the dangerous precedent of the United States providing unlimited financial support to a country that poses no genuine systemic risk to the US financial system (or to the global financial system).

The moral hazard is obvious: Why should any country pursue painful but necessary reforms when they can simply wait for a bailout? Why should Argentina fix its institutional problems when the US Treasury stands ready to finance its dysfunction?

Ultimately, this policy doesn’t just threaten US financial stability through the direct cost of supporting Argentina.

It threatens the entire architecture of international financial responsibility. When “systemically important” becomes a political designation rather than an economic reality, and when bailouts come with no strings attached, we’re not promoting stability. The US taxpayers will be subsidizing instability.

The world is indeed upside down when an “America First” administration puts Argentine bondholders before American taxpayers.

PS Back in July I warned about Milei not being the miracle maker that some was making him up to be in my blog post Classical Liberals, Let’s Be Honest About Milei
