This technical blog post explains OSTree and Bootc as Linux deployment technologies emphasizing reproducibility, system integrity, and atomic updates. While not explicitly addressing human rights, the article implicitly supports freedom of information through open-source knowledge sharing and promotes technical autonomy enabling users to understand and control their systems. The work reflects values compatible with UDHR principles around information access, scientific participation, and personal system integrity.
bootc and OSTree are both very neat, but the leading edge of immutable Linux distros (GNOME OS, KDE Linux) is currently converging on a different proposal by systemd developers that's standardized by the UAPI Group (https://uapi-group.org/specifications/). It fixes quite a few of the complexities with OSTree (updates are handled by `systemd-sysupdate`/`updatectl` and are just files served via HTTP) and is quite a bit easier to extend with things like an immutable version of the Nvidia drivers or codecs thanks to system extensions handled by `systemd-sysext` (which in turn are just simple squashfs files overlayed over `/usr`) and configuration via `systemd-confext`. `mkosi`, also by systemd, is quickly becoming _the_ way to build custom images too, and is somewhat tied to these new standards.
It is very odd to me to watch OStree-based distros starting to take off and win recruits.
The only reason Red Hat needed to invent this very complex mechanism was because RH does not officially have a COW-snapshot capable filesystem in its enterprise distro.
A filesystem with snapshots makes software installation transactional. You take a snapshot, install some software, and if it doesn't work right, you can revert to the snapshot. (With very slightly more flexible snapshots, you can limit the snapshot to just some part of the directory tree, but this is not essential; it merely permits more flexibility.)
In other words, you are a long way toward what in database language is called ACID:
Atomicity, consistency, isolation, durability. It makes your software inastallation transactional: an update either happens completely (A), you can check it is valid (C) and works (I), or it can be totally reverted, and the system restored to the earlier state (D).
That's a good thing. It means you can safely automate software deployment knowing that if it goes wrong you have an Undo mechanism. Databases got this 50+ years ago; in the 21st century it's making its way to FOSS OSes.
Do this in the filesystem and it's easy. SUSE's implementation is so simple, it's basically a bunch of shell scripts, and it can be turned on and off. You can run an immutable OS, reboot for updates, and if you need, disable it, go in and fix the system, and then turn it back on again.
This is because SUSE leans very heavily on Btrfs and that is the critical weakness -- Btrfs is only half finished and is not robust.
But RH removed Btrfs from RHEL and Btrfs was the only GPL COW filesystem, so core infrastructure in the distro means no COW on RH. Oracle Linux has Btrfs -- the FS was developed at Oracle, after all -- and so does Alma.
(Yes I know, Fedora put it back, but the key thing is, it only uses Btrfs only for compression so that Flatpak looks less horrendously inefficient. Fedora doesn't use snapshots.)
With no COW FS, RH had to invent a way to do transactional updates without filesystem support. Result, OStree. Git, but for binaries.
And yes, everyone developing FOSS uses Git, but almost nobody understands Git:
You know that if there's an Xkcd about it, it must be true.
Embedding something you don't understand in your OS design is a VERY BAD PLAN.
With OStree your FS is a virtual one, it's not real, it's synthesized on the fly from a local repository. The real FS is hidden and can't be hand-edited or anything. It generates the OS filesystem tree on the fly, you see. OS-tree.
Use it just for GUI apps, that's Flatpak.
Use it for the whole OS, that's OStree. It is so mind-shreddingly complicated that you can't do package management any more, you can't touch the underlying FS. So you need a whole new set of layers on top: virtual directories on top of the main virtual directory, and some bits with extra pseudo-filesystems layered on top of that to make some bits read-write.
It's like the scene in the Wasp Factory where under the skull plate it's just writhing maggots. I recall in horror and revulsion when I see it.
So it's deeply bizarre to read blog posts praising all the cool stuff you can do with it.

Eh, you don't typically have a lock mechanism for the filesystem equivalent to that of a database.
Who's to say something like this doesn't happen:
- snapshot fs
- op/system adjust firewall rules
- "you" install updates
- you rollback
- firewall rules is now missing patches
Don't get me wrong zfs is great - but it doesn't come with magical transactions.
