        Yes, exactly.

        I think ~all of those are install kernels, where the RB_SINGLE
        makes sense. The current situation where adding MEMORY_DISK_<FOO>
        changes the default boot behaviour to single user violates
        the POLS...

        I'm happy to do so. Be wary of amiga and atari where you have to
        modify the .in files rather than the generated kernel conf.

        Thanks!
