JumpStart is a computer network installation tool set used by the Solaris operating system.
JumpStart is used to manage operating system installation in many Information technology environments (corporate and otherwise) where Solaris operating system computers are widely used.
Technically, the network boot and install servers can be separate functions, but they are typically the same system.
Once a client system begins the JumpStart process, it then accesses the operating system component software packages stored on the JumpStart server, usually but not exclusively using Network File System.
Those packages, and optionally additional tools or applications, are automatically installed, and then the system is rebooted.
