I upgraded the GDS and ROOT installations in /ligo/apps/ubuntu12 the control room workstations:
My cursory tests indicate that they seem to be working:
Now that the control room environment has become somewhat uniform at Ubuntu 12, I modified the /ligo/cdscfg/workstationrc.sh file to source the ubuntu12 configuration:
controls@nodus|apps > cat /ligo/cdscfg/workstationrc.sh
# CDS WORKSTATION ENVIRONMENT
This should make all the newer versions available everywhere on login.
