Remote Boot Daemon

 The rbootd daemon is used for booting some HP workstations
 over the network (such as the 9000/300 and 9000/400 series).
 It can also boot some PA RISC workstations (such as the 9000/730).
 It handles the first stage of the boot sequence and can be used to
 start booting Linux, NetBSD or HPUX.
