I am sorry, but arguing over whether network filesystems have their
functionality outside the filesystem is not an argument I respect enough
to engage in. Clearcase is a filesystem. Views are built into the
filesystem.
It has user space utilities. It is still a filesystem despite having
user space utilities, and its functionality is in the filesystem.
