definately a bug.

there are certainly better solutions to this, but the one that
requires the least code would be something like this

for(disk in /dev/sd?[0-9]) {
	if(test -f $disk/data && test -f $disk/ctl){
		disk/fdisk -p $disk/data >$disk/ctl >[2]/dev/null
		if(test -f $disk/plan9){
			for(part in $disk/plan9*)
				disk/prep -p $part >$disk/ctl >[2]/dev/null
		}
		if not{
			part=$disk/data
			if(! disk/prep -p $part>[2=1] | grep -s '^no plan 9')
				disk/prep -p $part >$disk/ctl >[2]/dev/null
			parts=($disk/data)
		}
	}
}
