Introduction

I'm starting a new blog: I often do IT stuff I want to keep a trace of and I think it will fit in a blog. It may also help someone somewhere someday.

I've recently moved my daily device to (Arch-)ParticleOS, an image-based distribution built around immutability, measured boot, and much more, with a deep integration of systemd, as described in Fitting Everything Together. I am configuring things like isolation of my different environments, backups, custom services, etc. again. It is then a good moment to document to myself why I do this.

I've been following work for immutable systems and systemd for some time, and I've learned about ParticleOS during a talk at FOSDEM25. It's good to see that it finally exists, even if it's not yet ready for mainstream users.

And it's good to be back to Arch: I've been mostly using Fedora-based distribution after testing Qubes OS. My desktop was running on Fedora Silverblue, an atomic version of Fedora. Fedora Atomic Desktops shares some characteristics with image-based distributions. ParticleOS exists for Fedora rawhide too, but since it needs a rolling-release distrib (for now), I might as well get back to Arch.

I'll possibly talk about stuff I do on Android too, on Molly, UnifiedPush, or anything else.
