I know this thread is likely to quickly descend into 50 variants of “ew, snap”, but it’s a good write up of what is really a pretty interesting novel approach to the immutable desktop world.
As the article says, it could well be the thing that actually justifies Canonical’s dogged perseverance with snaps in the first place.
I appreciate that they try, and as much as I dislike some of snap’s design choices I think it has a place. Flatpak appears to be the winner in this race however, and I feel like this is Unity all over. Just as the project gets good they abandon it for the prevailing winds. I’ve been told the snap server isn’t open source, which is a big concern?
Unlike desktop environments where there were equivalent alternatives to Unity, Flatpak isn’t an alternative to Snap that can deliver an equivalent solution. You can’t build an OS on top of Flatpak. This is why I think that if Snap makes the lives of Canonical developers easier, they’ll keep maintaining it. We’ll know if Ubuntu Core Desktop becomes a mainstream flavor or the default one. I think there is a commercial value of it in the enterprise world where tight control of the OS and upgrade robustness are needed. In this kind of a future Snap will have a long and productive life. If it ends up being used only for desktop apps which Flatpak covers, it may fall by the wayside as you suggested.
Absolutely, and I think that’s why snap has a future at all. Immutability is the future, as well as self-contained apps. We saw the explosive growth of Docker as indication that this was the way. If they can make their tooling as easy as a Dockerfile they will win just by reducing the work needed to support it.
I’m pretty excited about it. It’s a much cleaner solution to the problem immutable OSes are trying to solve. Dare I say it’s better even than the Android model because it covers the whole stack with a single system.
I don’t like Canonical pushing snaps as universal apps for all distros, because of issues like sandboxing not working on mainline kernels.
But it’s pretty interesting to see how a fully snap based desktop OS could look like. It might have less limitations than rpm-ostree. Easy access to recent mesa and similar would be awesome.
I’m very excited about how the Linux community generally seems to be moving towards various approaches to immutable systems - all of them having in common that system updates are going to be a lot less likely to break. The future is looking good!
As long as we don’t end up with Linux systems designed like Android.
If anyone would lock their OS down like that, it would be Canonical.
“like android/ios” is the ultimate goal of these systems lol
Using Fedora Silverblue has gone a long way to dispel that concern for me. It goes out of its way to be much more user-centric than that. I can’t speak for the others yet.
“like Android/ios”
is pretty vague. Do you mean locked down, with features like SafetyNet which locks people in to Google Services? Or do you mean locked down in the sense that installing packages doesn’t just directly change the files in / ?
Systems like rpm-ostree still allow modifications to the OS, it just requires other steps. OpenSUSE MicroOS even allows for arbitrary modifications to the root fs through transactional-update (it even allows for dropping in to a transactional-update shell, so it’s not necessary to prefix each command with transactional-update).
Especially OpenSUSE MicroOS feels more like OpenSUSE Tumbleweed, compared to Fedora rpm-ostree’s limitations compared to Fedora dnf.
Having distro maintainers decide a rigid partition structure for you would be a really bad approach, so I really hope not.
Yes except it’s all open source and if you’re unhappy you can fork. Good luck forking iOS.
This is the best summary I could come up with:
Ordinary desktop and server Ubuntu aren’t going anywhere, and the next release, numbered 24.04 and codenamed Noble Numbat as we mentioned last month, will be the default and come with all the usual editions and flavors.
Nor is this a whole new product: it is a graphical desktop edition of the existing Ubuntu Core distro, as we examined on its release in June last year, a couple of months after 22.04.
Ubuntu Core is Canonical’s Internet of Things (IoT) distro, intended to be embedded on edge devices, such as digital signs and smart displays.
Most of the major Linux vendors have immutable offerings, and The Reg has looked at several over the years, including MicroOS, the basis of SUSE’s next-gen enterprise OS ALP.
Former Canonical staffer Alan Pope demonstrated a Steam Deck running Ubuntu Core at the event, and his lengthy blog post about the experience contains some interesting details about how well the developer preview already works.
Compression of Flatpak apps is a key reason that Fedora now uses Btrfs, although it’s worth noting that, as of yet, Snap doesn’t include any form of deduplication between separate packages.
