Runtime contents refer to data and states that are currently in use by the system at the time of the reboot. This includes the contents of memory, active processes, and temporary files that exist only for the duration of the system's operational state. When a system is rebooted, all runtime data is cleared, which means that any processes that were active, temporary configurations, and data stored in RAM are lost. This allows the system to start fresh, free from any previous operational states or data that might otherwise conflict with a new run of the operating system. On the other hand, static, dynamic, and persistent contents refer to different aspects of system data: - Static data is typically part of the filesystem and does not change often; it remains until modified through specified processes. - Dynamic data can change frequently but, unlike runtime data, it might be written and saved back to a persistent storage medium, thus not being lost during a reboot. - Persistent data is written to disk and is intended to remain available even when the system is turned off, such as user files, configuration files, and system settings. The focus on runtime data being cleared during a
