Betsy noticed that the BS screen was in a bad state, with gains and offsets and matrix values not filled in, despite the fact that I'd done setup on it back on 2/18 (alog 5440). It turns out it was because although I'd created /opt/rtcds/userapps/release/sus/h1/burtfiles/h1susbs_safe.snap there was no symbolic link /opt/rtcds/lho/h1/target/h1susbs/h1susbsepics/burt/safe.snap pointing to it. So after the various restarts between now and then it was not getting correctly restored. I created the link and checked that the correct settings were loaded when I restarted the model.
