The command "rpm-ostree install ${package} --reboot" is used in a system that utilizes "OSTree" as a package management system. It is commonly found in systems like Fedora Atomic Host, Silverblue, and CoreOS.
Let's break down the command:
-
"rpm-ostree" is the command line tool used to interact with the OSTree package management system. It manages the operating system's base layer and allows atomic updates.
-
"install" is the subcommand of "rpm-ostree" that is used to install new packages or layer them on top of the base image.
-
"${package}" is a placeholder that should be replaced with the name of the package you want to install. It represents any package available in the repository.
-
"--reboot" is an option that is added to the command to automatically trigger a system reboot after the installation. This is often necessary in systems that use OSTree for package management since the base image is mounted read-only, and changes made by the installation need a reboot to take effect.
So, when you run the "rpm-ostree install ${package} --reboot" command, it installs the specified package on the system using the OSTree package management system and then triggers an immediate reboot to apply any changes made during the installation.
