ZDNET’s key takeaways
- ShaniOS is an immutable Linux distribution.
- With a blue/inexperienced deployment, the OS won’t ever break.
- You possibly can obtain and use ShaniOS at no cost.
Working system safety has all the time been a trademark of Linux. With the introduction of immutable distributions — CoreOS, launched in 2013, was among the many first — no different working system might come near the extent of safety Linux needed to provide.
I welcome any alternative to check a brand new immutable Linux distro. Over the weekend, I found ShaniOS.
Additionally: Immutable Linux delivers serious security – here are your 5 best options
ShaniOS is an Arch-based Linux distribution that’s immutable and consists of Flatpak integration. The important thing options of this new OS embrace:
- Immutable core with blue-green deployment
- Flatpak utility administration
- Enhanced safety with AppArmor profiles, firewalled configurations, and full-disk encryption
- Efficiency optimizations comparable to dynamic swap file creation and Nvidia GPU assist
What’s blue-green deployment?
Utilizing Btrfs subvolumes, the system maintains two full system states — labeled “blue” and “inexperienced.” Just one state is energetic at any time, so atomic updates and rollbacks can happen with the best stage of reliability.
For instance, should you’re utilizing the blue setting, updates are utilized to the inexperienced setting after which examined. You possibly can then change from the blue to the inexperienced setting throughout a reboot. In different phrases, you’ll all the time have a working occasion of your OS, with out fail.
Additionally: What is immutable Linux? Here’s why you’d run an immutable Linux distro
If one thing goes fallacious with one setting, reboot and change to the opposite.
Open a terminal and concern the command sudo shani-deploy and watch the magic occur. The command does the next:
- Downloads updates for the inactive setting.
- Applies the updates with out affecting the energetic setting.
- Configures the bootloader to make use of the up to date setting.
- Ensures immediate rollback functionality in case the replace doesn’t work correctly.
As a result of that is an immutable system that leverages the blue/inexperienced strategy, functions are managed in two methods:
- Flatpak for desktop apps
- Containers for improvement apps
Additionally: 7 Linux commands I can’t live without after 20 years in the terminal
I ran the sudo shani-deploy command, and it took a complete of seven minutes and 40 seconds. Please be aware that I’ve solely been testing the distribution for just a few days, so there is not quite a bit put in. Had I put in loads of functions and saved loads of information, that point would almost definitely be significantly longer. Nonetheless, the command ran flawlessly, and I might change from one setting to the opposite upon the following reboot.
What ShaniOS is like
You possibly can obtain a model of ShaniOS with both GNOME or KDE Plasma. I went the KDE Plasma route and located the UI to be fairly pretty. The builders have tweaked KDE Plasma in order that it seems distinctive however nonetheless features very equally to the default desktop setting.
Additionally: 5 Linux distros that take a little work out of the box, but are so worth the effort
You may discover the desktop menu within the high left nook (versus the underside left), and the theme is good and glassy. The preinstalled utility record consists of Vivaldi, OnlyOffice, Warehouse (for Flatpak app administration), KolourPaint, Pods (container administration), and extra. Though it is probably not an intensive record of preinstalled apps, you possibly can all the time launch KDE Plasma’s Uncover app and set up any further software program you want. As a result of Flatpak is baked into Uncover, you may discover tons of apps to put in.
There are tons of apps to put in on ShaniOS.

Exterior of the hanging KDE Plasma theming, one of many first issues that impressed me was how briskly ShaniOS carried out. I’ve used quite a few immutable Linux distributions earlier than, however I do not recall testing one which carried out in addition to this one.
I additionally examined the blue/inexperienced environments. Whereas utilizing the blue setting, I ran the sudo shani-deploy command. When the deploy command completed, I rebooted and chosen the inexperienced setting. The whole lot was flawless. I used to be even alerted to check the apps to make sure they work as anticipated — which they did.
Whereas operating the inexperienced setting, I created and saved a file to the Paperwork listing. I then ran the shani-deploy command, solely to be alerted that there was a boot mismatch and that the system anticipated besides blue however discovered inexperienced was operating.
The perfect distro for brand spanking new customers
I then remembered that the OS alerted me to check functions to make sure they work, after which reboot to use the whole lot. I adopted the directions, and the adjustments have been utilized to the blue setting, leading to the whole lot being precisely as anticipated.
Additionally: I install these 11 apps on every new Linux system, and you should, too – here’s why
This method is absolutely spectacular. Actually, ShaniOS has me pondering that immutable Linux distributions may be the best choice for brand spanking new customers as a result of they’re so bulletproof. And with the blue/inexperienced deployment scheme, ShaniOS may properly be the most effective of the most effective.
I extremely advocate giving this immutable Linux distribution a try to seeing if it would not impress you as a lot because it did me. Seize both the GNOME or KDE Plasma version, set up it on a spare laptop (or as a digital machine), and expertise this improbable working system.
