/sys$common/syshlp/helplib.hlb AUTOGEN, Phases, REBOOT  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    REBOOT automatically shuts down and reboots the system, thus
    installing the new parameter values. To install the new system
    parameter values generated in the SETPARAMS phase, specify either
    SHUTDOWN or REBOOT as the end phase. You can define the logical
    name AGEN$SHUTDOWN_TIME (using the DCL command DEFINE) to specify
    the number of minutes before shutdown occurs.

    REBOOT requires the SETPRV privilege.
