ZDNET’s key takeaways
- RakuOS is a hybrid immutable/commonplace Linux distro
- With RakuOS you get one of the best of each worlds with safety and value.
- RakuOS could be downloaded and put in totally free.
Immutable Linux is about as safe as an OS can get. By mounting sure directories as read-only, malicious code or dangerous actors can’t have an effect on the info inside. I might severely place my full religion in immutable Linux and never fear a few factor.
Till I wished to put in an utility utilizing the distribution’s built-in package deal supervisor.
With immutable Linux distributions, software program is usually put in through containers, akin to Flatpak or Snap. Set up of apps is completed this manner due to the read-only nature of sure directories. Due to that, commonplace package deal managers can’t set up the mandatory recordsdata, so utilizing the likes of apt, dnf, or pacman is a no-go.
Additionally: What is immutable Linux? Here’s why you’d run an immutable Linux distro
Does that imply you are restricted to the apps you’ve gotten obtainable on an immutable distribution? Considerably. Do not get me mistaken, the typical person will not really feel as in the event that they’re lacking out on something as a result of Flathub and Snapcraft have tons of apps.
However after I’m utilizing an immutable distribution, and I need to set up one thing like Ollama, I am out of luck if I need to guarantee I am utilizing the most recent model of the app (I at the moment run Ollama 0.30.7 on my Pop!_OS desktop). I’ve tried to put in Ollama through Flatpak, and though the command completes, the app is nowhere to be discovered.
I’ve tried a number of instances, however the finish result’s a failure. Nonetheless, working the command sudo dnf set up ollama works simply high-quality; it should not, but it surely does.
Why ought to the DNF command fail? As a result of RakuOS is immutable, putting in through DNF should not be doable. That is the place RakuOS says, nay, nay. How does RakuOS pull this off? In accordance with the official web site, “RakuOS makes use of a persistent overlay system mounted immediately on /usr. Your base system is all the time pristine — however you possibly can set up any native package deal you need, and it survives each system replace.”
Additionally: How to run a Windows app on Linux with Wine
With this hybrid system, you get:
- An immutable base system with on the spot bootc rollback.
- Native packages that mechanically persist throughout updates.
- Permits set up through dnf, dnf5, or the RakuOS Software program Middle.
- A pristine system reset with a single command (extra on that in a bit).
- Flatpak for sandboxed apps (heightened safety) and native packages for every part else.
In different phrases, you get one of the best of each worlds.
My expertise with RakuOS
The RakuOS desktop won’t be essentially the most elegant desktop in the marketplace, but it surely’s nonetheless fairly particular.

The factor I appreciated essentially the most about RakuOS is that, whereas it had the entire underpinnings of an immutable distribution, it nonetheless felt like a conventional Linux OS. The one distinction was that as an alternative of the KDE Plasma Uncover app retailer, there was the RakuOS Software program app retailer. The excellent news is that the RakuOS Software program app appeared and behaved equally to that of Uncover.
The RakuOS App Retailer is kind of user-friendly.

With RakuOS, I used to be capable of set up the entire software program I usually would use through a mixture of Flatpak and DNF. If I wished to put in an app with the added safety of isolation, I used Flatpak; in any other case, I dove into DNF.
Additionally: 5 Linux distros that take a little work out of the box, but are so worth the effort
So far as efficiency is anxious, RakuOS makes use of the CachyOS kernel, so it is constructed for velocity. It doesn’t matter what I threw on the desktop, it did not bat a watch. Even working a hefty Ollama question (writing a Python GUI app) did not sluggish the machine down.
It is laborious to beat the CachyOS kernel.
Jack Wallen/ZDNET
That CachyOS kernel is one thing particular, and the RakuOS devs have been good to incorporate it.
However then, my curiosity bought one of the best of me, and I made a decision to attempt the “pristine reset” choice to see how properly it labored. After putting in a number of apps and saving some recordsdata/knowledge to my dwelling listing, I scoured the RakuOS web site for any point out of the particular command used for this, however discovered nothing.
Given how RakuOS creates the overlay in /usr, I believed, “What occurs if I merely take away every part in /usr? Could not damage, proper? I’m working RakuOS as a digital machine, so if it does FUBAR the system, I can spin up one other VM with out a lot hassle.
Ergo, I issued the command:
sudo rm -rf /usr/
That was a bit nerve-racking.
A fast restart to see what the outcomes have been, solely to seek out the restart failed. I pressured the VM off after which restarted. The boot course of took significantly longer than I’d have anticipated, however then, provided that I might nuked the /usr listing, I am pondering perhaps RakuOS needed to rebuild it.
Additionally: I tried a Linux distro that promises free, built-in AI – and things got weird
Perhaps?
I waited, and waited, and waited.
Does not say.
As soon as extra unto the breach with a reboot, and the identical subject continued. Time to reinstall. This time round, I remembered that RakuOS was based mostly on OSTree, so the command was easy:
sudo rpm-ostree reset
Even somebody who’s used a bit of know-how for many years can get tripped up at times.
The second time round, every part went properly, and I wound up with a pristine OS (after set up, use, and resetting with the correct command).
My remaining thought on RakuOS is that this: I am impressed. This Linux distribution offers customers one of the best of each worlds: immutability with the power to make use of default package deal managers. Though set up takes a bit longer than I am used to, the top end result may be very a lot well worth the time invested.
When you’re searching for an OS that’s equal components safe and user-friendly, give RakuOS a attempt. You may download an ISO for the KDE Plasma, GNOME, or COSMIC variations, create a bootable USB driveand set up it.
When you’re already working a Fedora Atomic-based distro, you possibly can reset with:
sudo rpm-ostree reset
After which you possibly can rebase to RakuOS with one of many following instructions:
