This is the usual poorly thought out argument, which fails to note that 
when you lose a disk you're already screwed due by /etc/fstab and the 
need to hard-mount local filesystems.

The "right" solution is and has always been to name your disks and mount 
them by name.  Once devfs is a reality, we'll be able to do just this.  
Until then, the problem's not really as bad as you make it out to be.
