- <Pete-J> Hello i am just curious of the development of Hurd - what's the
- current mission on the microkernel i see projects like l4 and viengoos,
- will one of these projects replace Mach? or will you stick with Mach
- <Pete-J> as i understand is that Mach is a first generation microkernel
- that's very old in design and causes alot of issues
- <Pete-J> that's where l4 and viengoos comes in - they are trying to be the
- next generation Mach - am i correct?
- <neal> l4 is not a drop in replacement for Mach
- <neal> it doesn't actually do much resource management
- <neal> for instance, you still have to implement a memory manager
- <neal> this is where several issues are with Mach
- <neal> l4 doesn't address those issues; it punts to the operating system
- <Pete-J> and what about viengoos?
- <neal> it's unfinished
- <neal> and it implemented some untested ideas
- <neal> i.e., parts of viengoos were research
- <neal> there has not been a sufficient evaluation of those ideas to
- determine whether they are a good approach
- <Pete-J> meaning that viengoos is a research kernel that could aid Mach?
- <neal> I'm not sure I understand your question
- <Pete-J> Well is viengoos trying to be a replacement for Mach, or will
- viengoos be an experiment of new ideas that could be implemented in Mach?
- <Pete-J> i am sorry for my limited english
- <neal> viengoos was designed with a Hurd-like user-land in mind
- <neal> in that sense it was a Mach replacement
- <neal> (unlike L4)
- <neal> viengoos consisted of a few experiments
- <neal> one could implement them in mach
- <neal> but it would require exposing new interfaces
- <neal> in which case, I'm not sure you could call the result Mach
- <Pete-J> Well as i understand you develop two microkernels side by side,
- wouldnt it be more effective to investigate viengoos more and maybe move
- the focus to viengoos?
- <antrik> no
- <antrik> having something working all the time is crucial
- <antrik> it's very hard to motivate people to work on a project that might
- be useful, in a couple of years, perhaps...
- <Pete-J> Well Mach is meant to be replaced one day - i see no reason to
- keep on developing it just because it works at this moment
- <Pete-J> *if Mach is meant to be replaced
- <antrik> it's not at all clear that it will be replaced by something
- completely different. I for my part believe that modifying the existing
- Mach is a more promising approach
- <Pete-J> as i understand man power is something you need - and by spreading
- out the developers just makes the progress more slow
- <antrik> but even if it *were* to be replaced one day, it doesn't change
- the fact that we need it *now*
- <antrik> all software will be obsolete one day. doesn't mean it's not worth
- working on
- <antrik> the vast majority of work is not on the microkernel anyways, but
- on the system running on top of it
- <Pete-J> ahh i see
- <antrik> manpower is not something that comes from nowhere. again, having
- something working is crucial in a volunteer project like this
- <antrik> there are no fixed plans
