Does this request actualy make sense?
Since file systems types don't overlap, if you explicitly include
one file systems type you implicitly exclude all others.
Thus there is no point in specifying a list that both includes
and excludes file system types.
For it to make any sense you would need file system type groups
(eg local, remote, M$, etc)
