The word "reboot" stands for the process of restarting a running device, i.e. it involves shutting it down and immediately starting it up again. The root of the word can be taken as advice: Get the device into its boots (i.e. running) again.
As the excerpt describes, this tag is intended for reboot issues. Examples include:
- boot loops (the device rebooting itself over and over without stop)
- getting stuck at a reboot (i.e. being forced to switch off/on the device to complete the boot process)
- sudden and unexpected reboots (happening without being requested by the user; "random restarts")
- after-reboot issues ("always after a reboot xyz happens / abc is lost / ...")
