TL;DR: How can I make permanent changes to the system and where do I parse drive status?
I'm attaching some indicator LEDs to the chassis. The user of the determining script might require the dialout group so I need to know to permanently add a group. I will be using a device that is attached to an internal USB 2.0 header, probably a ESP32. I know OMV salts/hashes after modifications but I don't know how or where/where-not.
Three things I need.
1. Where to parse the drive status data.
2. How to permanently add a script as a daemon without conflict/blocking something else OMV related that is unknown to me. I don't really want to run Docker to keep this 1 thing friendly/isolated.
3. How to permanently add a group, although I don't technically need the dialout group. That said, I haven't used Vanilla Debian in a while, so I might.
