#Indicates whether scl utilities will create 'permanent' mountpoints
#for all imported device partitions. (They are permanent in that
#they will persist until the disk is deported).
#
#Note that on W2K3 Enterprise, by default, devices cannot be
#accessed without either a driveletter assignment or a mountpoint
#assignment. Hence turning on 'no_permanent_mountpoints' may prevent
#MatrixServer from operating properly.
#
#Set to 1 to disable creation of permanent mountpoints.
#(default behavior is that scl will create permanent mountpoints
#for all imported devices.)
