           Summary: users has full read/write access to local harddrive on
                    thinclient.
           Product: Skolelinux
           Version: etch-alpha
          Platform: Other
        OS/Version: other
            Status: NEW
          Severity: normal
          Priority: P2
         Component: debian-edu-install
        AssignedTo: debian-edu@lists.debian.org
        ReportedBy: klaus@skolelinux.no


When the user looks in /media/$USERNAME he will have full read access to the
harddrive in the thinclient. This is not what one might expect, and is a
disaster in i lot of real-life settings. One such real-life setting where that
would mean trouble is in schools where they sometimes use teachers laptops to
get extra clients during special times, for example when they have exams, and
they need to double the number of available machine for a short time. 

Oh, when the harddrive contained windows(ntfs) the disk was read-only, but when
the harddrive had linux, it was read/write!
