Maybe it would help if we thought about it like this:
--what are the available 'root directories' on the system
on Unix this there is always one: "/"
on Dos there are several possibly: "A:\ C:\ D:\" etc
Then from a functional point of view we need to be able to retrieve this list of
directory entry names regardless of platform. I haven't followed this whole
discussion lately, but I see no reason why this can't be a directory iterator
since the results would all be directory names. It's just that with unix we
will only iterate once since there is only one root....

Even with Beman's desire to avoid global data, we still need a function that can
return the current working directory of the process. From the working directory
name it should be possible to obtain the current root directory name. So I
don't think we want root_directory() to return the 'current' root. I haven't
looked at the latest proposal to see if what I suggested is really covered,
