I'd prefer that to validate the command-line doesn't have multiple 
variable names, or the variable name specified before the -bootable 
flag, so that only the following options are valid:

... var
... -bootable var

and not:

... var1 var2
... var -bootable

etc.

This could be tightened up later I suppose. Other than that, this series 
looks good at a quick glance, so:
