Hey there,
using balenaCloud, Device Configuration tab and clicking on the edit button of any user field, I got help texts like e.g. "Edit RESIN_HOST_CONFIG_dtoverlay"
Hey, thanks for raising this issue! Currently the supervisor will support both the RESIN_ and BALENA_ prefixes, so don’t worry about using the wrong one!
But you’re absolutely correct we should get this cleaned up in the UI. I’ve opened this GH issue for tracking and we’ll let you know when we have a fix! Or feel free to submit a PR!
