[Bug 879710] Re: ubuntu-vm-builder crashes when trying to umount tmp directory.

[Sylvester Rajasekaran]

Hi

Based on some of your comments I tried to find what was the issue with the "umount" 
The below command helped me to get the information who is holding the lock so based on Serge Hallyn (serge-hallyn) request the error shows as follows, (lsof didn't help me much here so I used fuser)

-----------------------------------------------------------------------------------------------------------------
#  fuser -f -v /tmp/tmp4WlrLItmpfs

                                           USER        PID           ACCESS               COMMAND
/tmp/tmp4WlrLItmpfs: root     kernel           mount                 /tmp/tmp4WlrLItmpfs
-----------------------------------------------------------------------------------------------------------------

Based on the above information where I can not kill the PID becuase
"kernel" is holding the lock.

So what would be my option here?

Thanks
