Naming of directory from which to load kernel modules

        (Thread on renaming directory from which to load kernels
        modules from /stand to /kernel switched from source-changes
        to tech-kern - please drop source-changes from any reply)

        I suspect what may be needed is a searchpath for modules, based
        on at least the kernel version and potentially the kernel name,
        eg, booting a /onetbsd of version 5.99.4 would look in
                /${kernel}/modules-onetbsd-5.99.4
                /${kernel}/modules-onetbsd
                /${kernel}/modules-5.99.4
                /${kernel}/modules

        The first matching path found would be used for all modules - no
        'mix and match' from different directories

        Replace ${kernel} with top-level-directory-of-choice, which
        may or may not be /kernel

        Some people prefer /kmods, some /kernel, some /stand, and there
        are probably other preferences.
        One question - would people anticipate some users keeping the
        kernels in this directory as well? so you could boot
        /kernel/onetbsd ?
