Module Name:

    bootvrfy.c

Abstract:

    This is a small service that simply calls NotifyBootConfigStatus to
    indicate that the boot is acceptable.  This service is to go at the
    end of the service dependency list.

    The assumption is that if we got far enough to start this service, the
    the boot must be ok.
