Immutable Linux for low end PCs? (lemmy.world)

I have a laptop with 4 GB of RAM that I'd like to use for occasional comic book reading. (It's a touch screen 2-in-1 laptop that folds over into a tablet configuration.) I use Bazzite on my main PC and I love how low maintenance it is. Are there any immutable/atomic distros that featue XFCE, LXDE, or some other low RAM friendly desktop? Or, should I just layer XFCE or LXDE on top of UBlue Core or make my own image or something? Thanks!

VanillaOS and OpenSUSE immutable ones use BTRFS snapshots dont they? Not sure how VanillaOS does their A/B root.

These systems always involve copying things around and deduplicating them.

Filesystem snapshots are well deduplicated, nixos does that well too though.

For openSUSE's atomic offerings, you're correct. Vanilla OS is a bit more nuanced, though. I don't quite recall how they did it on their original images. But since Orchid, there is a reliance on OCI images for its updates. Note that bootc is also contingent upon OCI images, which is why I made the comparison earlier. They behave so similar to one another, that Vanilla OS' Vib can be used (without too much trouble) to create Fedora Atomic images.

As for the usage of Btrfs snapshots on Vanilla OS, I think it doesn't quite need it because it relies on lvm thin provisioning instead for its ABRoot. However, an attempt to verify this by installing it within a VM failed spectacularly and I don't think the blame is on me 😅...
