rpm-ostree VS distrobox

I definitely agree that immutability offers considerable value in regards to improving security. But arguably it's insufficient to pull the win over mutable Fedora due to the losses caused by the inability to install the kernel-hardened package and the lack of UKI (Unified Kernel Image) support.

Issue: https://github.com/coreos/rpm-ostree/issues/3944

Oversimplifying might have been the most sensible in this context. However, you might have gone a little bit too far as your description fits only NixOS, Guix and distros that utilize rpm-ostree.

here's the documentation of ostree (the package manager)

Now... this was VERY alarming to say the least, so I went online and did indeed find an issue on GitHub.

And there are still some issues with layering. Some packages that don't behave or follow standards will modify files in /usr/local, which isn't supported, so you simply won't be able to install them on Silverblue. I think it's the same for /opt as well. (https://github.com/coreos/rpm-ostree/issues/233) This means it fundamentally can't do everything Workstation can, which is unfortunate.

ublue is based off of fedora and rpm-ostree, which is what "CoreOS" is today.

What happened was old school CoreOS was A/B partition based: https://github.com/coreos/docs/blob/master/os/sdk-disk-parti...

My memory is hazy but here's how I remember it: After Red Hat acquired CoreOS they rebased the entire thing around rpm-ostree, which is the CoreOS people know today: https://coreos.github.io/rpm-ostree/

At the time there was some anxiety in the community as to what would happen, as there was no direct upgrade path from old CoreOS to new CoreOS. Theoretically if we all believed the kool-aid we were drinking it's just a redeploy, no pets!

Kinvolk came along, forked it, and made Flatcar Linux, which kept the A/B partitioning system, and more crucially, let you just change a config file and all your old CoreOS nodes would just move to Flatcar and then you were good to go. So now if you wanted to stay on the system you were comfortable with you could just use Flatcar. If the composability of rpm-ostree attracted you then new CoreOS have you covered. Red Hat deserves a hat tip here because in their documentation/blog they explicitly mentioned Flatcar as an option for people who wanted to stick with what they know, which I thought was cool and how I discovered it!

Later on Microsoft acquired Kinvolk and and then people raised eyebrows. I have not checked in a while but the folks involved continued to do their thing and run it like a good OSS project, hold public meetings, all that stuff.

I use both and they're both high quality.

Whenever I was looking at using CoreOS, I was somewhat disheartened that automatic reboots weren't built in: https://github.com/coreos/rpm-ostree/issues/2831. Has this changed? I know zincati has maintenance window support, which would also be nice to have.

Doesn't look like it https://github.com/coreos/rpm-ostree/issues/1091

Distrobox is a tool that enables us to try Linux distro CLI, including their package manager. This requires a containerization tool (e.g., Docker). In Windows, this can be achieved using WSL (Windows Subsystem for Linux)

I use containerized versions of things, ubuntu and chainguard images mostly.

You can always create containers with init if that's how you want to do that though. Some distros publish images that come that way: https://github.com/89luca89/distrobox/blob/main/docs/useful_...

Yes, you can do that but I've seen others use something like distrobox to run linux inside of SteamOS: https://github.com/89luca89/distrobox/blob/main/docs/posts/steamdeck_guide.md

For such cases you might use something like this: https://github.com/89luca89/distrobox

Btw #3: Depending on what the user is trying to accomplish, e.g. maybe to make WSL(2) itself more of a "subsystem" than a "container engine", using something like Distrobox or nsbox.dev can be a good idea (along with Docker or Podman in Distrobox's case; the other one uses systemd-nspawn).

1. Find here in "Containers Distros" section the distro image that you want to install ("Toolbox" versions are better because they are configured for Distrobox) and get it URL: https://distrobox.it/compatibility/#containers-distros 2. Use that URL to create Distrobox: distrobox create -i registry.fedoraproject.org/fedora-toolbox:39 -n fedora_1_39 3. Enter Distrobox fedora_1_39: distrobox enter fedora_1_39 4. You are already in Distrobox console. Look at the name in console, it should be include the container name. 5. To exit Distrobox: exit 6. If you run: distrobox list you will see all distroboxes on the system. You will also see that distrobox that we exited is still running. 7. To stop distrobox use commands: distrobox stop fedora_1_39
