## What it is
rpm-ostree is a hybrid image/package system for RPM-based Linux distributions that combines libostree's checksummed, transactional image model with RPM package management via libdnf. It provides atomic upgrades and rollbacks, client-side package layering, and tools for composing custom base OS images.

## Use cases
- atomically upgrade an immutable Fedora CoreOS or Silverblue host
- layer additional RPM packages onto an ostree-based OS without breaking atomicity
- roll back to the previous OS deployment after a bad upgrade
- compose a custom base OS image from RPMs for edge or server fleets
- manage kernel arguments and initramfs configuration transactionally
- upgrade the OS in the background without disrupting running workloads

## When to choose
- you run an ostree-based distribution like Fedora CoreOS, Silverblue, or CentOS Stream CoreOS
- you need atomic, rollback-capable OS upgrades with package layering
- you want to build custom bootable images from RPMs for immutable infrastructure

## When to avoid
- you use a traditional mutable distro where dnf alone suffices
- you are starting a new bootable-container project - bootc and dnf5 are the recommended path
- you need non-RPM package formats like deb or apk
