Thanks for this link!

"antiX is my top pick for truly constrained hardware. It runs on systemd-free Debian Stable, uses around 256MB at idle, and includes a full desktop experience. The trade-off is a less polished interface compared to Ubuntu-based options. If you need something even lighter, Puppy Linux runs entirely in RAM and can resurrect machines that most distros would reject. The learning curve is steeper, but the performance is unmatched."

I would actually recommend Bodhi Linux for under 2GB. https://www.bodhilinux.com/ I installed AntiX on a 2GB Chromebook, and it had issues crashing on browsers under even a couple tabs. It might have just been the laptop I bought from Goodwill, or the fact that I disabled swap, because it was an old 16GB soldered SSD/NAND drive that I wanted to avoid heavily writing swap space to. https://www.youtube.com/watch?v=VhozuNv-J7Q

Bodhi is more featured with a more conventional package manager than Puppy, and while I like booting from RAM, it's learning curve is a little steeper and less maintained than Bodhi, which is getting a new release soon: https://www.reddit.com/r/bodhilinux/comments/1qqrfyj/is_bodh...

I did a video with Bodhi on Virtual box with 1GB since I didn't have the Chromebook with me at the time, but it idles around 350MB (possibly before Chromium running): https://youtu.be/61xI-g--ozs?si=y7ukxyEGSj_kNPF7

For additional package manager support, a nice UI (Enlightenment) and compatibility, it's far more preferrable than 250MB ideling on AntiX with less support.

For Atom N450 series, I recommend eXe Linux: https://exegnulinux.net/ I have a video of that too.

I hadn't heard of BunsenLabs, but I will definitely check it out (Note: Atom N450 chips support 64 bit, even on single core, so they might work great on those machines)
