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.

Make any Distro Immutable (github.com)

It is by design non-invasive and should work on any distro which meets the requirements; Btrfs root and systemd-boot bootloader. With non-invasive I mean; it doesn't mess with your normal OS and its configuration, it can be rolled out, toyed around with and just as easily be removed again.

Taken from reddit:

I think this is the best approach to immutability. I don't want heavy abstraction and I don't want containers.

A system I can deploy anytime and rollback on is all I needed.

When I have time, I will include this in my setup.

Why no containers?

This community is full of people who simply "don't like certain things". They may say "it's overkill" disregarding the fact that it solves their use case perfectly. Or it could be written in a language they don't like. Or maybe they heard somebody else complain about it on a forum once and now think it's bad.

I think flatpaks are good. The performance penalty for containerized software can be felt much more when you're not using a good CPU. So containers do not "solve" my use case.

I'm using a cpu from 2013 and gaming in containers seems to work as well as it does outside of containers.

Yeah, it’s also the same group of people who are always complaining about how much RAM a desktop environment or app uses, that app being whichever one they are using right now.

Sounds great but needs more contributors to gain trust so that it can be used in production.

and systemd-boot bootloader. With non-invasive I mean; it doesn't mess with your normal OS and its configuration

Well, there's the problem...

[–] [email protected] 4 points 9 months ago (1 children)

I much prefer it over grub. I don't think there's any other bootloader's that support btrfs snapshots.

There's this.

To get a truly immutable experience install use squashfs instead :D

[–] [email protected] 2 points 9 months ago (1 children)

Could you pass me a link to an example setup?

[–] [email protected] 4 points 9 months ago

It's a joke; squashfs is read-only :D Stuff's used on routers and similar stuff
