Package Management
There are two types of {MAJOROS} system; "traditional", which use DNF, and "image-based" which use rpm-ostree.
Traditional package management
On a traditional {MAJOROS} system, software is divided into RPM packages, which can be managed via [application]*DNF*.
Hybrid image/package management
The "Atomic" variant of {MAJOROS} uses [application]*rpm-ostree* to update the host. `rpm-ostree` is a hybrid image/package system. By default, installations are in "image" mode using OSTree, but additional packages can be installed. It also supports overrides, rebases, and many other features. For more information, see link:++https://www.projectatomic.io/docs/os-updates/++[its online documentation].
Additionally, the `atomic` CLI supports installation of system containers, which are Docker/OCI images distinct from the host user space. For more information, see link:++https://www.projectatomic.io/docs/usr-bin-atomic/++[its online documentation].
