Can't read the 84 pages now but if I'm not mistaken Hurd and L4 are both (micro)kernels. I don't understand what it means to port a kernel to another kernel. It would have made sense for me if they had ported the GNU tools to work with L4. Can somebody enlighten me ?

Hurd is the higher level services of a micro-kernel, but uses existing kernels for the actual part in kernel space (normally GNU Mach). So this would be replacing Mach with L4, retaining Hurd for the user space operating system components.
