Thanks!  Now I don't have to the merge the patch anymore :)

Good idea, I should have done that.  Did you fix up all the indenting problems
introduced by the patch?  I avoided all the whitespace changes to keep the
patch small.

Um, let's see... I worked out all this stuff a year ago...

The head node gets this:
   mkdir /pvfs-meta
   (  
      cd /pvfs-meta
      $PVFS_MKMGRCONF -r /pvfs-meta -u $2 -g $3 -m 700 -H $(hostname) -p 3000 -P
   7000 $(echo $(sort $PBS_HOME/aux/$JOBID | uniq | head -$PVFS_MAXNODE))
   )
   $PVFS_MGR

And every node in the job (including the head node) gets this:
   mkdir /tmp/pvfs-data
   chown $JOBUSER:$JOBGROUP /tmp/pvfs-data
   echo -e "datadir /tmp/pvfs-data\nuser $JOBUSER\ngroup $JOBGROUP" > /etc/iod.conf
   
   echo $EXE_HOST:/pvfs-meta /scratch pvfs port=3000 0 0 > /etc/pvfstab
   
   [ -d /scratch ] || mkdir /scratch
   $PVFS_SBIN/iod
   $PVFS_SBIN/pvfsd
   $PVFS_MOUNT $EXE_HOST:/pvfs-meta /scratch

Nope, mkmgrconf is writing the .iodtab for me.
