 Actually.. I think the easiest solution, that would keep the current
 functionality of assuming you want to operate on your boot disk, would be to
 embed a short list of disk drivers into the utility, and if bootdev isn't one 
of
 those, just drop usage.  (we only have like 5 or 6 disk drivers in the tree,
 and it hardly has to be kept up to date, as in reality, you probably only care
 about fd, sd and wd)
 
 However, short of that, I think its much much more rediculous to attempt to
 open my network device's raw partition.  The error it spits out is completely
 nonsensical.
 
 I could also see it's guessing be rather dangerous, if your root disk is a
 raid, it defaults to that:
 
 polaris# fdisk
 fdisk: primary partition table invalid, no magic in sector 0
 fdisk: Cannot determine the number of heads
 Disk: /dev/rraid0d
