Deployment Guidelines

slsDetectors will automatically install its dependency slsDetectorsPackage.

For debugging purposes it can be useful to have tshark installed on the control server, and xctrl user added to the wireshark group.

The control server should have a 10 GbE network interface for sending images to the DAQ, and possibly one for the GUI server.
