for the person who administers the Linux FailSafe system. The Linux FailSafe
administrator must be familiar with the operation of the appropriate storage
subsystem configurations, such as the configuration of any raid systems or
fibre channel systems which will be used in the Linux FailSafe configuration.
 Good knowledge of mirroring, the filesystems used, and any volume management
system to be used is also required.</para>
