I can't stress how useful this has been over the last few years!  A 
recent kernel upgrade moved IDE HDs into the same module as SATA, and 
now my /dev/hd* are /dev/sd*.  No problems though, since I never refer 
to those devices directly (granted, most of it is over raid as well, and 
that autoscans).

I use encrypted swap, and the first step there is to attach a loopback 
on a device and do a mkswap on it.  Now, just imagine what would happen 
if that device suddenly pointed to something important?
