While I’ve looked into Fedora Silverblue, that distro is limited to only install Flatpaks, which is fine for “apps”, but seems to be more of a problem with managing system- and CLI tools.
No. Your understanding to Fedora Silverblue is wrong. I can just run rpm-ostree install package.name in Silverblue, like other Fedora spins. The small disadvantage is that I need to reboot to apply this update. (re-construct)
but doesn’t that result in new A/B snapshots, or something like that?
Well, you can call it snapshots, but there is no need to think about it. In most cases, the system points to the newest snapshot (deployment 0). If a rollback is needed, I can pin to the older deployments. When a major change is to be applied (Like bump Fedora version), I’d manually mark the current deployment as dont-auto-delete.
Sure, but I’d like to have a more seamless experience, i.e. not having to open/start any “containers” or something like that.
I never used toolbox in my Fedora Silverblue system. I feel that I can’t tell the difference between using Silverblue and the default Fedora spin
