  PROBLEM
 
       This problem only occurs with AIX versions prior to 3.2.4.
 
       Due to a defect in the pax command, restoring from a mksysb
       tape can result in all of the files being owned by root.
       The pax command checks the /etc/passwd file and, if the
       owner of the file is not listed, makes root the owner.
       Since the real /etc/passwd file is on the tape, the default
       passwd file (which does not have entries for any of the
       users) is used.  This has been corrected by APAR IX30655
       which is part of the 3.2.4 PMP tape.
 
  WORKAROUND
 
       The mksysb tape has saved the proper ownership for the
       files, and you can change the files to their proper owner-
       ship with the following steps.
 
       1.  Mount the mksysb tape and run the following script.  It
           will create a file with the necessary commands to
           correct the ownership of the files.  NOTE:  The script
           can be modified to fit special requirements.
 
              cd /tmp
              tctl -f /dev/rmtx rewind
              tctl -f /dev/rmtx.1 fsf 3
              tar -tvf /dev/rmtx |
                 awk '{ if ( NF == "9" )
                 printf ("chown %s.%s %s\n",$2,$3,$9) }' > mksysb.out
              chmod 755 mksysb.out
 
           After running the above script, you can edit mksysb.out
           if you wish to make any changes to it before executing
           it.

       2.  Execute the file "mksysb.out".  It will change all the
           files to their correct ownership.
