How is the *BSD and MacOS drive sharing && dual booting work coming
along? Any status updates from our Port-master?

The only environment it changed was real-base when booting w/2.0f1
to MacOS. It maintained across reboots into OFW. I can't confirm any
better than that unless the end result would be me taking a 15lb sledge
hammer to my G3. One of these days in the very distant future I'll try
learning PPC assembly and Forth...............and MIPS, 68k, 88k asym,
etc.
