Questions on Dealing with Multiple Places

[Rubusch]

Hi, this is probably rather a "discussion" than an "issue"...

Currently I'll have around 8 places. A place consists of a DUT and a RPi with the labgrid-exporter(s) as systemd service, [labgrid v24.1]. Originally I liked to put my 8 RemotePlaces into one target "lab" in the exporter config. Then I used 8 different client environments. Doing it as in the configs down below, I could merge the client environments into one. But now I end up with 8 targets, providing the same name as RemotePlace. I know similar things were described in the documentation, but I could not figure out, neither found examples (this might be the small issue: please provide some .yaml examples with multiple RemotePlaces).

Questions:

1. What is the difference between a "target" and a "resources/RemotePlace" from a setup point of view?
2. Isn't there a way to declare a single target "lab" and in the client environment do a list of several "RemotePlace" names? Can you provide a snippet for this case?
3. Most configs are the same, but some will have the usbsdmux attached, so as below UNIT01. So, how to merge redundant parts of the labgrid-client config, and setting up individually additional features?
4. I need several NetworkService e.g. on UNIT03 I need a NetworkService on 1.2.3.49 (RPi) and another one 1.2.3.50 (DUT) - how to configure this case for the labgrid-exporter and for the labgrid-client?
5. Also open for further issue in my configs.. I'd like to implement power control rather as driver, but this will be another issue. Somehow this approach fits me currently.
