RS CHANGES: - RS retains information on both labels and process names now. Labels for boot processes are configured in the boot image priv table. Process names are inherited from the in-kernel boot image table. - When RS_REUSE is specified in do_up, RS looks for an existing slot having the same process name as the one we are about to start. If one is found with an in-memory copy of its executable image, the image is then shared between the two processes, rather than copying it again. This behavior can be specified by using 'service -r' when starting a system service from the command line.
