I offered my experiences because I believed (and still do) that it is 
common to have / and /var on separate partitions on the same drive.  I 
also think it is easy to overlook the huge performance penalty with 
bayes defaulting to /.  Moving bayes to /var was dramatic enough (a 10 
fold reduction in IOWait time) that I believed it was worth sharing with 
others who may have the same setup.  That's why I posted.
