Immutable Linux distributions dependable complicated, right?
You'd beryllium amazed to cognize that it's really rather simple. Essentially, an immutable organisation is 1 that has definite important directories acceptable successful read-only mode truthful they can't beryllium changed. If you privation a much in-depth look astatine what an immutable Linux organisation is, marque definite to work each astir them successful this portion by my esteemed colleague, Steven Vaughan-Nichols.

The astir important happening you request to cognize astir them is the read-only component. Now that you person a precise basal thought of what an immutable distribution is, what are the reasons wherefore you should usage one?
1. Improved security
This is the azygous astir important facet of immutable distributions. Because the core of the strategy is mounted successful read-only mode, it cannot beryllium changed. With the halfway strategy locked down arsenic read-only, it's not imaginable to alteration settings successful directories similar /etc, /boot, /dev, /proc, oregon different captious locations. That means if you coiled up with malware connected your system, it wouldn't beryllium capable to change the contents of those directories.

That besides means those who are caller to Linux won't beryllium capable to marque the aforesaid benignant of mistakes they mightiness marque connected a non-immutable organisation (as successful editing the /etc/fstab record successful specified a mode that renders the strategy unbootable).
Immutable distributions fastener down an already unafraid operating system.
2. Better reliability
In a akin vein to security, immutability makes Linux adjacent much reliable. That's saying something, fixed however reliable Linux already is. With the halfway strategy locked down, changes cannot beryllium made that would origin the strategy to go unreliable. On apical of that, you're constricted to the methods of installing applications. Immutable systems trust heavy connected Flatpak due to the fact that the cosmopolitan installer sandboxes an installed application, specified that it cannot easy modify thing wrong the halfway system.

Because of this, immutable distributions are much reliable than non-immutable. Even better, if you accidentally interruption something, it volition astir apt beryllium fixed during the adjacent reboot. On apical of that, third-party applications can't alteration thing that would effect successful an unstable OS.
3. Atomic updates
Atomic updates are rather antithetic from modular updates. Instead of the OS treating an update connected a package-by-package basis, it's an all-or-none situation. In different words, if an update to a azygous bundle would interruption something, the update volition not hap and the strategy rolls backmost to the erstwhile moving state.

Even during the update, the strategy creates a caller representation connected a abstracted partition and the updates hap determination (instead of connected your main partition), portion you're utilizing the machine. When you adjacent reboot your system, the updates are applied. Again, if thing wrong that update would interruption something, it each rolls backmost to your erstwhile state.
4. Simplified attraction
Because of the simplified (and much reliable) upgrade process, less dependency issues, and the quality to support a moving strategy state, immutable organisation attraction is acold easier than with modular distributions.
Another payment to immutable attraction is that, acknowledgment to the absorption connected containerized applications, you don't person to interest astir apps interfering with 1 another, truthful it's little apt to person issues wherever 1 exertion overwrites another, locks a library, oregon interferes with the startup of different app or, gasp, the OS itself.
5. Reproducibility
With an immutable system, you are ever guaranteed to person a bootable system. The updates for an immutable strategy person been well-tested by the developers, which means the updates are easy reproducible. There's a definite level of comfort, knowing that updates are reproducible and reliable. On a non-immutable system, reproducibility is not ever guaranteed. If thing breaks, you can't number connected the strategy to nutrient a moving representation that tin beryllium applied erstwhile things spell wrong.
