           Summary: supermount allows mounting same dir twice in mdk-9.1
                    final
           Version: 2.4.21-0.13mdk
          Platform: Other
        OS/Version: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
        AssignedTo: [EMAIL PROTECTED]
        ReportedBy: [EMAIL PROTECTED]


I have supermount enabled. An entry in my /etc/fstab looks like this: 
 
        none /mnt/cdrom2 supermount 
dev=/dev/hdd,fs=auto,ro,--,iocharset=iso8859-1,codepage=850,umask=0 0 0 
 
Initially, "cat /proc/mounts" shows only one entry (as expected): 
        none /mnt/cdrom2 supermount ro 0 0 
 
Now, I mount /mnt/cdrom TWICE and the system indicates no error !! The "Used by" field 
of 
lsmod for supermount also goes up by one everytime I mount thus showing that 
supermount is 
aware of it. Also, "cat /proc/mounts" shows 3 identical entries now: 
 
        none /mnt/cdrom2 supermount ro 0 0 
        none /mnt/cdrom2 supermount ro 0 0 
        none /mnt/cdrom2 supermount ro 0 0 
 
How can a cd device be mounted more than once to the same mount point ? This is very  
strange. I reported an identical bug in bug 2105 but that was marked as resolved and 
"fixed" 
even though the bug is very much there in mdk-9.1 final.
