Not OP but I will add to the conversation from my own experience:
I have been using Bazzite for over a year now, and I haven’t seen any changes reverted, everything works perfectly fine just as the day I first installed it. It just works. It’s been very easy for me to migrate from Windows thanks to this distro. I distrohopped and tried every major distros (10+), most of my issues were either outdated GPU drivers or unstable OS for noobs like me. Bazzite fixes those issues.
The gist of it is that it’s the easiest distro I’ve ever used. Just go to bazzite.gg and try it.
- GUI apps: use the app store that ships with Bazzite (called Discover)
- CLI apps or libraries: use Hombrew (open terminal, type for example: brew install pandoc)
- if you can’t find what you want either in Discover or Homebrew, the developer might ship it in a portable format called Appimage, you can easily “install” it using the included Gear Lever app. Alternatively, you can install packages meant for pretty much any distro using Box Buddy (built on top of distrobox).
Bazzite is described as atomic but not fully immutable because of how it handles system updates while allowing user modifications.
Atomic Updates
- Transactional Updates: Bazzite uses rpm-ostree, which applies updates in a transactional manner. This means updates are downloaded and applied as a whole, and the system reboots into the updated version. If something goes wrong, it can roll back to the previous version.
- Layered Packages: Users can install additional software as an “overlay” on top of the base system without modifying the core image.
Not Fully Immutable
- Unlike some truly immutable OSes (e.g., Vanilla OS in “ABroot” mode or Ubuntu Core), Bazzite allows modifications:
- Users can install extra software using rpm-ostree install.
- The system has read-only root by default, but users can override this with rpm-ostree override replace or rpm-ostree reset.
- Flatpaks, AppImages, Distrobox and Homebrew, don’t affect the base OS. You can install and uninstall software to no avail and it won’t brick your OS installation.
Thus, Bazzite provides atomic updates via rpm-ostree, ensuring stability and rollback capability, but it remains modifiable, making it not strictly immutable.
Identify your Windows drive and your secondary drive, install Bazzite (bazzite.gg) on a secondary drive, you’ll be able to test how it runs on your hardware. If you want to keep it, then just chose whatever you want to boot to using your bios. You can set one of them to default, and you can temporarily boot to the other by pressing your motherboard’s designated boot key (usually F11 or F12, look up yours).
