I’m new to Fedora and I have a few questions:
1. Is silverblue also rolling release? 2. Which distribution is secure and does not threaten to crash or break the system? 3. Only the silverblue edition has “containers”?
I would like rolling release and ideally such a distribution that will not break by mistake. Is Silverblue or CoreOS choice for me better? Is it worth waiting for Fedora 31 and then installing, or does it matter?
Fedora is not a rolling release and it is stable. Silverblue is still under development and testing so you’d better install the regular Fedora release. You can install Fedora 30 now and then upgrade to Fedora 31 when it is released and all major bugs are fixed. You can work with containers on any Fedora version. CoreOS is a minimal system targeting “the cloud” so it is not suitable for workstation/server use.
Fedora Silverblue is a new variant of Fedora Workstation with rpm-ostree at its core to provide fully atomic upgrades. Furthermore, Fedora Silverblue is immutable and upgrades as a whole, providing easy rollbacks from updates if something goes wrong. Fedora Silverblue is great for developers using Fedora with good support for container-focused workflows.
Additionally, Fedora Silverblue delivers desktop applications as Flatpaks. This provides better isolation / sandboxing of applications, and streamlines updating applications — Flatpaks can be safely updated without reboot.
CentOS Stream will be a rolling-release Linux distro that exists as a midstream between the upstream development in Fedora Linux and the downstream development for Red Hat Enterprise Linux (RHEL). It is a cleared-path to contributing into future minor releases of RHEL while interacting with Red Hat and other open source developers. This pairs nicely with the existing contribution path in Fedora for future major releases of RHEL.`
