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 starting to think people misunderstand what an "immutable" distro really does...
Please do share with me what I do not understand.
A mostly read only filesystem built from a limited number of packages, with other files being in a fixed number of locations mean it is harder for malware to hide.
You can achieve the exact same thing with a normal distro if you mount /var and /boot separately of /. And if you get a root exploit it's just as harmful on either approach.
"Immutable" systems are meant for maintainer comfort not for user security.
No, you can't : in an immutable distro I can reasonably trace almost any file in the filesystem back to the package that created it, and know with a reasonable degree of certainty that the installed version of said file has not been tampered with. That isn't possible an a normal distro.
Sure it is, has been for decades. You can use a read-only root partition, there are many tools to ensure the integrity of everything on it, and tracing files back to their package is a very old feature.
