Perhaps it would be better to have this defaulted on install to *not* use 
LABEL= mounting syntax.  In that case, the broken device would have prevented 
mounting and, therefore, booting and the problem of dropping half the mirror 
leading to this corruption would not happen without FRAID users knowing about 
it.  Yet another case where mounting using LABEL= syntax causes more problems 
than it solves.
