Barring the traversal of a symbolic link, it's impossible to start on
one volume and wind up on another.  There is no "root of the

Not possible unless folder1 is actually a symbolic link (== alias in

Say what?  File::Spec::rootdir returns '' (except under MacPerl

MacPerl, it returns the startup volume, which isn't the root directory
but is useful behavior.)
