IMO a mounted file system per se should be represented by an object, and then
that object should have the methods to deliver generic or file-system-specific
file and path and walking objects etc.

After all, even NT can see DOS partitions, vs NTFS vs raw floppy
and HD images of potentially foreign formats. And my slackware linux sees one DOS partition
that can be alternately booted, but can read from slackware via a mount.

Cf. another post in this thread (which didn't get any response ;-)
