Frank, the part which says ``run a special userspace utility?''
is a big step *backwards*.
Try inserting an MBR-labelled CF into a USB CF reader. Or inserting
the same CF into an IDE laptop slot, via a CF-to-PCMCIA mechanical adaptor.
You're saying NetBSD users will have to remember to run Bill's special
usespacer utility on each insertion? Before they can even *see*
what's there to mount? I dunno about you, but that strikes me as poor
engineering.
Now I'm not suggesting we put the whole shebang into the kernel. That
doesn't seem worth it. But putting *everything* (except the minimum
needed to boot) into userspace is, I think, going too far in the other
direction.
