With future multiuser support in mind, no program should ever write
settings to any other place than ~/config/settings. I believe this has
always been the Be philosophy anyway, so this should already be the
case, right? How about making /boot/home a ramdisk when running off a
read only volume? That way everything should work as usual, but
changes would of course get lost on reboot (so a notice of this when
the desktop appears would be good, perhaps in a simple window that
also lets you start the installer?)
