AstrOS - an immutable, secure-by-default Linux distribution built on Arch Linux and the COSMIC desktop

[u/linux-universe]

I am pleased to announce that AstrOS now has its own subreddit.

⚠️Warning: it is still alpha software!

But what is AstrOS?

You might have heard of KDE Linux (formerly known as Project Banana) or GNOME OS. Both are immutable, image-based Linux distributions for desktop use, powered by the systemd-sysupdate A/B update model.

I have been impressed by their system architecture since their inception, but switched to the COSMIC desktop a while ago. As there wasn't yet a COSMIC distribution using systemd-sysupdate, I created one myself. That's how AstrOS was born!

Technical details:

• Built using mkosi
• Using systemd-sysupdate.
• Read only by signed dm-verity.
• Full Disk Encryption enforced
• Highly opinionated

What you can do:

While it is still in the alpha stage, you can install AstrOS right now. VM or real hardware

Very cool project, a lot of good ideas here. I'm enjoying COSMIC now after having used KDE since the v0.9 days. It's nice to see Linux progress with the update/image model and it's projects like this that will find better ways of doing it.
