[TriLUG] non-root partial view of file?

[Igor Partola]

What Bill said. The answer may be as simple as "the mount command lets you
mount a volume over any path in the FS, including /bin, which would be
bad". Perhaps, though I have no direct knowledge of this, mount cannot be
written with file permissions in mind because it's used at some lower level
where these things don't exist yet. Or perhaps it's not user permissions
aware for legacy reasons.
