Architecture: amd64
Machine: amd64
>Description:
        Several key manual pages describing various aspects of
        booting an amd64 system are missing from /usr/share/man/man8/amd64
        but they appear in the i386 equivalent. Those that are
        appropriate to both ports should be cross-linked.
>How-To-Repeat:
        Login to NetBSD/amd64 system.

        % man boot

        notice references to boot_console(8).

        % man boot_console
        man: no entry for boot_console in the manual.

        go looking, and find /usr/share/man/man8/i386/boot_console.8
>Fix:
        Determine which of the man pages in /usr/share/man/man8/i386
        also apply to amd64, and change the appropriate Makefile
        to see that they are linked in there.
