The System V version of this command is available with the System V software installation option. Refer to Installing SunOS 4.1 for information on how to install and invoke baby. Most systems require con- stant monitoring when baby reaches its final stages of execution. Older implementations of baby required that the initiating process not be present at the time of completion. In these versions the initiating process is awakened and notified of the results upon completion.
Modern versions allow both parent processes to be active during the final stages of baby.
Parent processes then typically broadcast messages to all other processes informing them of their new status in the system. FSF version of baby where none of the authors will accept responsibility for anything. Everyone is weird. Some of us are just proud of it.
