sysback is backing up NFS mounted filesystems

Env:
  AIX 4.1.4
  RISC SP2
  sysback 3.3.2.10

Desc:
  During a full system install the /usr/sys/inst.images filesystem
  fulls up.

Action:
  I had the customer check on the server system where the backup
  was created, on /usr/sys/inst.images filesystem.  It appears
  the customer has a jfs filesystem mounted first, then a 
  nfs mounted filesystem right on top of it.  Instead of 
  ignoring it (the find command) it is printing out all the
  files in that nfs mount.  So the backup is now backing it up and
  on the restore restoring it.  So it is very easy to run out of space
  in the jfs filesystem during the restore.

WORK AROUNDS:
   Restart the install
   increase the size of /usr/sys/inst.images
        OR                    
   unmount the nfs filesystem and recreate the backup

        OR
   Add this entry in this command /usr/sbin/mkvgback
      cp /usr/sbin/mkvgback /usr/sbin/mkvgback.org
      vi /usr/sbin/mkvgback
        change this line:
        cmd="$cmd\\tfind .$dir ! -type s -xdev $days -print\\n"

      TO

        cmd="$cmd\\tfind .$dir ! -type s -fstype jfs -xdev $days -print\\n"

Next Action:
  Passing to level three for possible bug in sysback

Next Action:
  This fix will be added to sysback 3.3.2.12
  Sending this version to the customer
  Closing with customer approval
