I see that MIDAS installs several set-uid-root programs into /usr/local/bin.
In this age and time of evil computer hackers, this is not a good idea and
we should Do Something (TM) about it. Here is my risk assessment:

Indeed the ODB command "cleanup" really works. I have used it several
times with the TWIST DAQ and regularly with the BNMR/MUSR setups where
we have these stubborn clients (ie feepics) that do not want to shutdown
