{bb} Using bbaliasname under NFS bb installation

[riches@ms.washington.edu]

I don't know if anyone else has run into this, but here what I did to deal 
with the situation.  Hope it helps someone else in the future!

I am setting up Big Brother (bbc1.9h) on an OpenMOSIX cluster.  The bb 
user is in the NFS-mounted home directory.  Each of the cluster nodes has 
an internal (OpenMOSIX private network) hostname and an external (user 
login) name.  Our bb server is external to the cluster and I want each of 
the nodes to report using its external name.  This is tough using the 
bbaliasname mechanism, since the nodes all share the same bb user 
directory.

I got around this by modifying the Big Brother code and changing the name 
of the file to reflect the output of the hostname command.  Here's what I 
did:

  - I modified this Big Brother code file:

      /home/bbro1/bbc/etc/bbinc.sh

    Here are the diffs for the change:

36,38c36,38
<
< if [ -f "$BBHOME/etc/bbaliasname" ]; then
<         MACHINE=`$CAT $BBHOME/etc/bbaliasname`
---
> BBALIASNAME="$BBHOME/etc/bbaliasname.`uname -a | cut -d\  -f 2`"
> if [ -f $BBALIASNAME ]; then
>         MACHINE=`$CAT $BBALIASNAME`


  - I created a file for each of the nodes in the cluster:

     $BBHOME/etc/bbaliasname.nodeN

    This file contains the public name of nodeN
