    SubjectDriver Model 2 Proposal - Linux Kernel Performance v Usability
    Following my initial post yesterday please find attached my proposal for a 
    binary 'plugin' interface:

    This is not an attempt to have a Microkernel, or any move away from GNU/OSS
    software. I believe that sometimes the ultimate goals of stability and
    portability get lost in the debate on OSS and desire to allow anyone to
    contribute. It is worth remembering that for every Kernel hacker there must
    be 1000's of plain users. I believe this proposal would lead to better
    software and more people using it.

    1. Implement binary kernel 'plugin' interface
    2. Over time remove most existing kernel 'drivers' to use new interface - This
    is NOT a Microkernel.
    3. Design 'plugin' interface to be extensible as possible and then rarely
    remove support from interface. Extending interface is fine but should be done
    in a considered way to avoid interface bloat. Suggest interface supports
    dependant 'plugins'
    4. Allow 'plugins' to be bypassed at boot - perhaps a minimal 'known good'
    5. Ultimately, even FS 'plugins' could be created although IPL would be
    required to load these.
    6. Code for Kernel, Interface and 'plugins' would still be GPL. This would not
    prevent the 'tainted' system idea.

    Expected Outcomes

    1. Make Linux easier to use
    2. The ability to replace even very core Kernel components without a restart.
    3. Allow faulty 'plugins' to be fixed/replaced in isolation. No other system
    4. 'Plugins' could create their own interfaces as load time. This would remove
    the need to pre-populate /dev.
    5. Remove need for joe soap user to often recompile Kernel.
    6. Remove link between specific module versions and Kernel versions.
    7. Reduce need for major Kernel releases. Allow effort to concentrate on
    improving Kernel not maintaining ever increasing Kernel source that includes
    support for the 'Kitchen Sink'
    8. Make core Kernel more stable. Less releases and less changes mean less
    bugs. It would be easy to identify offending 'plugin' by simply starting up
    the Kernel with it disabled.
    9. Remove need for modules to be maintained in sync with each Kernel thus
    freeing 'module' developers to add improved features or work on new projects.
