Yeah I think letting you make a system-wide decision like never make 
snapshots and/or backups is much better than trying to manage the 
passing of the arguments all over the place when there is one spot where 
you simply make your decision ... it's also why I've split the scripts 
up into pieces so the decision to make pre/post backup/snapshot is 
independent of the actual work being done ...

normally I would expect you to change the setUpSys or rebuildSys scripts 
themselves unless you have additional structure that you want to build 
at that point ...
