 +Ugly step.  If you look at /etc/hosts you'll see what we mean.  All blade host names should be unique, so we're going to fix some files.
 +
 +  * first installer hostname command comes back with 'kusu101'
 +  * copy /etc/hosts to /etc/hosts-good.  edit later.
 +  * put installer lines together, put 192.168 and 10.10 lines together
 +  * for 10.10 remove all short host names either 'kusu101' or 'node00' etc
 +  * for 192.168 add 'kusu101' or 'node00' etc short host names to first word after IP
 +  * leave all the other host names intact (*.kusu101, *-eth0, etc)
 +  * copy hosts-good across hosts file
 +
 +  * next do the same for hosts.pdsh and only use short host names, one name per node
 +
 +  * next do the same for /etc/lava/conf/hosts, use only 192.168 IPs and only one (short) host name
 +
 +  * next edit /etc/rc.d/rc.local and add lines
 +    * cp /etc/hosts-good /etc/hosts
 +    * cp /etc/hosts.pdsh-good /etc/hosts.pdsh
 +    * cp /etc/lava/conf/hosts-good /etc/lava/conf/hosts
 +
 +  * in /etc/cfm/compute-centos5.3-5-x86_64_BSS 
 +    * link in all the *-good files
 +    * make the rc.d directory at appropriate level and link in rc.local
 +  * run 'cfmsync -f'
 +  * on installer node run /etc/init.d/lava stop, then start and do this on nodes via pdsh
 +  * 'pdsh uptime' should now list the hosts with short name
 +  * 'bhosts' should in a little while now show the hosts as available
 +  * 'lsload' should do same
 +
 +  * copy
