Make any Distro Immutable in c/linux@lemmy.ml

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

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.

Could you pass me a link to an example setup?

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.

bcachefs? (programming.dev)
 

I was wondering if anyone here has attempted the new "COW filesystem for Linux that won't eat your data".

It's supposedly has been stable since the start of 2023. I'm willing to give it a try on Arch, but before I do, I'd like to hear if anyone has faced any issues with it.

"subvolume - cannot be snapshotted if it contains any active swapfiles"

Make a subvolume only for the swapfile.

has a chance to fragment

This is true for all files. Is it a bigger problem for swap?

has issues with hibernation (that I've personally encountered multiple times)

This one I can't refute. How long ago did you have these issues?

Mount options also only take effect on the first mount of the device. Since it looks like you only have 1 btrfs device - only / needs the options, really.

I didn't know this. Thanks!

Yeah it's supported. It's listed in the docs for btrfs and arch.

Help on BTRFS setup (programming.dev)
 

I'm attempting a new install. I want to use btrfs with swapfile.

Do I need to disable compression on my swap subvolume?

Is there anything else I should keep in mind for fstab if I want to, say, not keep track of my Downloads folder when snapshotting?

Here is my fstab:

What's with all these hip filesystems and how are they different? in c/linux@lemmy.ml
[–] actual_patience@programming.dev 1 points 11 months ago (1 children)

Don't you need FAT 32 for compatibility?

ext4 boot partition? Does that mean you have Coreboot, not UEFI?

Such a good image 🤣🤣🤣

Arch or NixOS? in c/linux@lemmy.ml
[–] actual_patience@programming.dev 1 points 11 months ago

I think you are understating the value of the Arch Wiki and AUR.

I am also a university student. I was required by one of my courses to program an Arduino using ArduinoIDE. My program, however, was not detecting my Arduino. By simply scrolling the Arch wiki, I found the issue, downloaded the fix via AUR and was able to get it working hassle-free. An equivalent of this process does not exist on NixOS.

I do not know what programs your uni requires, but if you do plan on using them on Linux, Debian or Arch, or their many derivatives should be the go-to simply for documentation and quick-fixes alone.
