If a person (a novice, no one reading this should assume there will one day be any useful result from my intention to try this) intended to attempt a powerpc port of hurd would he be better off working with L4, OSKIT-Mach, Mach 1.3, or OSF Mach (ie looking at Peter Bruin's work) as the kernel?
Pick what will require the smallest amount of time to port and get working. L4 falls out since the Hurd doesn't run on it yet, GNU Mach 1.x and 2.x, and OSF Mach are essentially the same, so picking either of them will do I guess. Maybe OSF Mach will be a better choice since Peter Bruin has already done some work.
