The problem is that you can't be sure that the new device that softraid
attaches will be sd1. For example if you have a umass(4) connected when
you boot things will get mixed up.
Earlier today I thought about writing a script based on the
hw.sensors.softraid0.drive0 sysctl value which will tell you whether it
has been attached correctly and what device was attached.
