Why use immutable Linux ? And which one ?
(lemmy.ml)
From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I'm pretty much immutable across the board on all of my servers and workstations (laptop included). Most my servers are openSUSE Leap Micro and MicroOS. Run MicroOS on the desktop side as well.
Honestly ....haven't had any issues and the maintenance of it is fairly hands off. Few of mine are k8s nodes so that combined with the reboot mgr + transactional-update has been awesome. I spend less time maintaining my homelabs / desktops and eases my focus in just getting work done.
I've only had to roll back a couple of times (mainly self-inflicted), so it's nice having that capability. A lot of this though can be accomplished in a non-immutable world as well.
A note on "MicroOS on the desktop": The Gnome variant is called OpenSUSE Aeon and the KDE variant OpenSUSE Kalpa. MicroOS branding is used only for server use due the confusing names. Quoting from https://news.opensuse.org/2023/05/31/microos-desktop-has-new-name/
