IIRC, Okuji among others talked about doing exaclty that. To me, it
seems like a good way to get going iff it really is reasonably cheap
port. As you say, once you have Mach running on L4, you would want to
replace Mach-dependent parts (like libports) one piece at a time.
Long term, it seems reasonable to run L4, a set of Hurd libraries and
servers, and then have things like device drivers running in userspace
using interfaces in L4, Hurd libraries, and OS-kit.
