Hello, I´m not a kernel expert, so I´ll not claim any technical knowledge about advantages or disadvantages of kernel design. But what is heavier, one pound of steel or one pound of feathers? You can only make an intelligent decision if you consider the tasks the software shall fullfill. The Hurd and the Linux kernel are fundamentally different in design, and they will both serve different needs. In fact, they will also share some code. Currently, the Hurd uses a lot of the Linux hardware drivers. the choice between Linux and Hurd is probably not even exclusive (although it´ll require a reboot to switch kernels). With binary compatibility, the user will have a choice to switch kernels (how far this can be supported I can´t tell. The Hurd will be able to run Linux binaries at least). Sorry Andrew, if I can´t tell you about the multiple kernel architectures and their advantegs and disadvantages. What is important here is that there´ll be a choice (and maybe not even an exclusive choice). Asking what the better kernel is may be comparable to the question what the better window manager is. "It always depends" seems to be the right answer. If you want to know for which tasks the Hurd system will performance best, I consider it a part of the Debian GNU/Hurd project to find out. Marcus PS: Some things you can already reckognize. For example, you can write hardware support without the nasty "hack, compile, reboot" cycle. Hardware support can be implemented in user space etc. This has influence on the possibility to write emulation for other hardware/systems, like Wine etc. -- "Rhubarb is no Egyptian god."
