We'd like to setup the recording of the PSL diagnostic connector Acromag channels in a more robust way - the objective is to assess the long term performance of the Acromag DAQ system, glitch rates etc. At the Wednesday meeting, Rana suggested using c1ioo to run the IOC processes - the advantage being that c1ioo has the systemd utility, which seems to be pretty reliable in starting up various processes in the event of the computer being rebooted for whatever reason. Jamie pointed out that this may not be the best approach however - because all the FEs get the list of services to run from their common shared drive mount point, it may be that in the event of a power failure for example, all of them try and start the IOC processes, which is presumably undesirable. Furthermore, Johannes reported the necessity for the procServ utility to be able to run the modbusIOC process in the background - this utility is not available on any of the FEs currently, and I didn't want to futz around with trying to install it.

One alternative is to connect the PSL Acromag also to the Supermicro computer Johannes has set up at the Xend - it currently has systemd setup to run the modbusIOC, so it has all the utilities necessary. Or else, we could use optimus, which has systemd, and all the EPICS dependencies required. I feel less wary of trying to install procServ on optimus too. Thoughts?
