This adds a new mechanism for rebooting, a form of "userspace reboot" hereby dubbed "soft-reboot". It will stop all services as in a usual shutdown, possibly transition into a new root fs and then issue a fresh initial transaction. The kernel is not replaced. File descriptors can be passed over, thus opening the door for leaving certain resources around between such reboots. Usecase: this is an extremely quick way to reset userspace fully when updating image based systems, without going through a full hardware/firmware/boot loader/kernel/initrd cycle. It minimizes "grayout time" for OS updates. (In particular when combined with kernel live patching)
