Fedora 22 Looks To Have RPM-OSTree For Atomic Upgrades

With Snappy Ubuntu being out there for atomic upgrades in the cloud and on servers, Fedora 22 is looking to have RPM-OSTree for providing atomic upgrades and server-side composes.

One of the latest features being proposed for implementing in Fedora 22 is rpm-ostree, which allows composing RPMs on a server in an OSTree repository to provide image-like upgrades with package-like flexibility. The rpm-ostree software was started by Project Atomic, an initiative around deploying and managing Docker containers.

Beyond making upgrades better, the potential for downgrades are also made easier by the system preserving the previously booted environment to allow for quick system rollbacks. This rpm-ostree support would be opt-in for new installations of Fedora 22.

While this feature has yet to be officially approved by FESCo, those wishing to learn a lot more about the rpm-ostree plans for Fedora 22 and prospects can visit the Fedora Project Wiki for details. Fedora 22 is currently shaping up to be a potentially very interesting release due out in May while the branching from Fedora Rawhide will take place in February.
