No, I put these files in the /root/scripts directory.
However, this is all outdated now that C+G released OS V3, which supports WiFi from the interface
EDIT: I see you already have OS3! – you should be good to go without this extra Linux wrangling. On the root of the USB stick, you should have a
wifi.txt file (you can create one if not), and fill it with your NetworkSSID and Password on two seperate lines, like this:
Then from the Organelle interface, go into the WiFi Settings and see if you can connect.
Also one thing I did have issues with was connecting to a 5G WiFi network (I use the Raspberry Pi CanaKit adapter). If you have control over your router, try creating a 2G network.
