Not for all architectures, only for the hurd system. Interfaces are usually a problem because they have to be kept around. If upstream introduces a similar, but not exactly same interface, then it becomes yet more difficult. Antrik, do you know an easy way to introduce RPCs in an sort-of "experimental" ID range, which would permit to introduce & test the RPCs without conflicting with future upstream assignation? > 2) How come execve calls a shell script works with . in PATH?
