It remains to be seen how successfully. The distribution loading code is still not here yet, but the partition/newfs/mount/cpio-extract cycle is as complete as it's ever going to get, modulo possible bug fixes. The TCP/IP setup screen is also sort of here, albeit in a highly-changing state due to the fact that per-interface information isn't being kept right now but is being added (thanks, Gary!).
