I use the Flatpak version of Firefox on Fedora Kinoite and it uses the KDE file picker without problems, I guess it’s an issue with the RPM version.

No idea, I try to avoid containerized software on desktops unless absolutely necessary like discord and jellyfin.

Ya, but you’re overlaying all that stuff, codecs, nvidia, etc. ublue works out of the box and updates are quicker due to not having to re-overlay everything. It’s just less friction. Also it comes with automatic updates enabled which is really nice (and safe in an immutable, intrinsically rollbackable environment)

Why ublue over fedora’s images?

Personally, I’ve been enjoying uBlue over vanilla Fedora Atomic for what they offer in terms of system management.

To give you a better idea on what I mean; just a month ago an update to Podman caused breakage and people weren’t able to use their containers created with Distrobox/Toolbx^[1]. Sure; a rollback is accomplished relatively easy and I’m sure some would even be able to fix it themselves. Regardless, every Fedora Atomic user that relied on Podman would have been interrupted to some capacity.

Which, of course, begs the following questions… Isn’t it very inefficient for everyone to fix this issue themselves? Wouldn’t it be easier if somehow Fedora forced some fix upon all of us so that just one entity is burdened instead of all of us? Heck, wouldn’t it be better if Fedora just withhold the update until it’s fixed? Is this perhaps some pipe dream that will never see the light of day? etc…

The interesting part, though, would be how I (a ‘uBlue-user’) didn’t even notice Podman was causing issues in the first place. “How?” you might ask, well… The uBlue devs noticed the issue, applied some magic so that I and many other uBlue users like me just went on with their day like they would otherwise; without being interrupted because Podman just had a bad update. (Did the supposed pipe dream actually already exist in some form or fashion?)

This is just the most recent example of this. But in the last year or so, out of the top of my head, there have been a few more times in which uBlue users didn’t even notice a thing while the others either had to rollback or fix their issues themselves. If you enjoy this interruption and/or are willing to deal with it for the sake of whatever, then please feel to continue to do so. However, I prefer to have a system I can rely on at all times and uBlue offers me just that while remaining very close to vanilla Fedora Atomic.

You won’t have fedoras signatures anymore.

It depends if you have the luxury to rely on them in the first place.

If setting up your workflow (or whatever) requires you to get to the nitty gritty of things and change those parts of the system that strictly speaking isn’t well supported by just rpm-ostree, then -for almost a year now- your best bet would have been to (instead) experiment with (what’s been referred in Fedora’s Wiki as) Ostree Native Containers.

And the truth is, unless you really know what you’re doing, that uBlue offers the best platform to engage with this system. Heck, within a week after Kinoite’s very own maintainer blogged about how to sign container images via Github actions, one of uBlue’s maintainers tried to implement this for uBlue to improve their own platform and succeeded.

Finally, let’s not forget that uBlue is even endorsed by Fedora (or at least by whoever maintains its documentation). Heck, even the inception of uBlue was due to an interaction between Jorge Castro (one of uBlue’s maintainers) and Colin Walters (one of the masterminds behind the whole rpm-ostree-ecosystem).

P.S. If I hadn’t made it clear, it’s totally fine to continue to rely on Fedora Atomic directly without any interventions from third parties for system management or whatsoever. I just wanted to elaborate why I, personally, prefer to use images provided by uBlue.

1. Source to a thread in which this is discussed.

I think most dual booters on Ublu use seperate drives for windows.

And use their BIOS to boot to that drive instead of grub.

FWIW, I’ve put some effort into explaining how a dual boot of Windows 10 and Fedora Atomic (read Silverblue/Kinoite/Sericea etc) can be achieved. While it’s far from exhaustive, it should be fine as long as your specific installation of Fedora Atomic doesn’t require special attention (which happens sometimes with owners of an Nvidia GPU*). After Fedora Atomic is successfully installed, proceed with following the instructions found on the following parts of uBlue’s documentation: here, here and finally pick whichever uBlue image you’d like to install from this list; specific instructions are found directly underneath the text boxes for each individual image, but ensure you’re installing the one with the correct Fedora version (37/38/39/stable/latest etc (which are accessed via tabs)). If you can’t decide on which version you’d like to install, then just go for 39.

Yes

Be careful with these containerized distros. I would read bit more before jumping into something not standard as of now. In particular, making changes to the root image by installing packages works a lot differently than good old Linux distros.

Otherwise Fedora’s KDE spin is quite good, too. They include a lot of extraneous packages, though.

Maybe I’ll give that a go for myself

Good luck!

they are starting to offer their own Laptops with pretty nice hardware it seems

Oh that’s neat, I must have missed those news, were they announced anywhere?

Opensuse is stupid fast + its very very stable. Would risk saying its unbreakable(at leaat with regular updates)
