advligorts-rcg runs a bash script with sh
'/etc/advligorts/env' has to source a legacy bash script that configures some environment variables for LIGO IFOS.
advligorts-rcg packaging calls '/etc/advligorts/env' using 'sh'.
The legacy script needs to be converted or dropped entirely, but also the packaging might be changed to use bash.
This bug currently breaks rcg install and upgrade. Work around is to comment out the bash source when installing the rcg then comment it back in.
