rpm-ostree Developer Colin Walters walters@redhat.com rpm-ostree 1 rpm-ostree Operating system upgrade and software management tool rpm-ostree COMMAND OPTIONS rpm-ostree is a system software management tool that combines features of both traditional RPM and OSTree. At the moment, there are only two available commands: upgrade and rollback. On an rpm-ostree managed system, the traditional yum and rpm tools operate in a read-only state. Instead, the underlying OSTree layer replicates a filesystem tree from a compose server. In this "pure replication" model, there is no dependency resolution on the client machines, nor any ability to add or remove packages. upgrade Download the latest version of the current tree, and deploy it, setting it up as the default for the next boot. By design, this has no effect on your running filesystem tree. You must reboot for any changes to take effect. rollback OSTree mananges an ordered list of bootloader entries, called "deployments". Each entry has a separate /etc, but they all share a single /var. You can use the bootloader to choose between entries. This command then changes the default bootloader entry. If the current default is booted, then set the default to the previous entry. Otherwise, make the currently booted tree the default. ostree1, rpm8
