Mini vMac, the Mac Plus emulator. Its configuration program can only  
be run within itself. So I need to write to a disk image to set up  
this bootstrapping environment. See:

http://trac.macports.org/browser/users/ryandesign/minivmac/Portfile?rev=44609

(Because of upstream changes I will have to revert back to that  
method, except now with Snow Leopard, I can't.)
