arch-linux-installation-guide VS awesome-immutable

I'm so addicted to it that I wrote an installation guide just to show off to my 'friends'. Even after months of not reinstalling, I can guarantee that I can install Arch from memory in less than 5 minutes. Arch is love, Arch is life

That's exciting! If you need any help installing, I did make an easier to understand guide, good for learning. Althought I recommend ArchInstall these days. I'm glad it can be the first experiment! I have a lot of work to do to get this thing stable. Depending on your DE/WM and other conditions, the script may throw errors so just be weary of that and don't think your system is messed up. It's just that I had no PC for 5 months and I've been back at coding for only a few days now. I rewrote the entire script and dropped probably 100 lines. Seems like I am understanding the logic behind it a lot more now and I should have a functional release this week https://github.com/wick3dr0se/Arch-Linux-Installation-Guide

You should definitely try Arch Linux! The documentation on the ArchWiki is amazing and the community is helpful. I wrote a guide on installing Arch Linux on 86_64 architecture devices and I also have a public repository on GitHub with a stripped version of my desktop with a script to automate the desktop enviornment setup. My setup uses i3wm, feh for wallpaper, thunar, xfce4 terminal, vim as IDE, very basic stuff. I made the guide, script just to make installation easier for myself, since reading the ArchWiki can be cumbersome to say the least

Check out my Arch install guide I recently made for self refrence and to assist a friend. I have instructions on there for GRUB/systemd-boot as boot loaders and NetworkManager/systemd-networkd for networking tools. I use systemd everything because it works very well and I've never had a single issue. Using GRUB in the past I had trouble removing it from multiboot setups and I'd have so much bloat from different themes and versions of GRUB. I prefer to install my boot loader directly in to my EFI system partition, mounted at /boot and then I can manage all my boot files and entries there. You should definitely check it out! systemd-boot auto detects Windows in the EFI partition. I would suggest using NetworkManager for a simple use case, it's configureless and setup just by enabling the service daemon

Interesting article!

My takeaways:

>"The current solutions involve packaging entire alternate runtimes in containerized environments. Flatpak, Snap, AppImage, Docker, and Steam: these all provide an app packaging mechanism that replaces most or all of the system’s runtime libraries, and they now all use containerization to accomplish this."

[...]

>"All of these technologies are essentially building

an entire OS on top of another OS

just to avoid the challenges of backwards compatibility."

This is basically using containers to replace all system libraries -- to insure that a downloaded binary app always works.

From this point forward, we'll use the term "API" to represent not just Linux kernel syscalls, but the totality of all library calls (system and otherwise!) used by a given downloaded binary application!

Observation: API (in-)consistency (AKA "Stability") one Linux version to another, one Linux distro to another -- is the real problem!

That's the real cause!

Because everything else, everything else, is effect, not cause!

The containerization, the bloated "everything but the kitchen sink" downloads, are the effect of the problem of API (in-)consistency!

Phrased a simpler way -- there is absolutely NO guarantee of consistency between the libraries, system and otherwise, of any two Linux distros!

So if a binary app is to run on all Linux distros -- then it had better damn well better make sure that the exact specific version of all of the libraries that it needs -- are managed by it, not the host operating system!

Containers and bloated library downloads -- are (unfortunately) currently necessary to provide this!

If you're simply in search of other immutable distros, then I would recommend you to look under the "Distributions" section on this page.

The answer to that question is out of scope for what is sensible to write in a comment. Also, because we're mostly still exploring what it is or rather what we'd want it to be. But if you're really interested, then I'd suggest you to dive into this wonderful resource. You don't have to go through everything that's found within. However, I'm sure there's something in there that peaks your interest and you can go from there.

Flatcar uses 2 partitions, A and B, you boot into one and then updates update the one that you're not booted into, when you reboot it it boots into the updated one. It's like Android: https://source.android.com/docs/core/ota/ab

I maintain an awesome-list of immutable resources here with a collection of talks and presentations from the people making the stuff: https://github.com/castrojo/awesome-immutable

However I'm currently focused on desktop stuff since the it's a fairly common pattern in cloud already, I should probably write it up.

Semi-related, a few of us have started a community around composable OCI fedora images, and one of our images is intended to be used as a home server built on CoreOS with ZFS, cockpit, and all the goodies you'd need. It's still fresh and we're looking for help if anyone's interested: https://github.com/ublue-os/ucore (Disclaimer: I helped start this project)

Some interesting links: https://github.com/castrojo/awesome-immutable

Found this page for you. It has lots of resources, including videos and guides, about all things Silverblue and other immutable Linux distros, and their tooling. Enjoy.

Note, I haven't tried these two distros myself, but I am strongly considering moving to such a system at the moment. Here is some reading material in case you're interested: https://github.com/castrojo/awesome-immutable
