Cool, I met someone else who had a similar use case which is part of why I decided to share this (not sure if should say who).
So it sounds like we are probably not going to go with the approach I proposed; if you indeed find this useful, I would suggest that we put this in our OpenBMC repository and switch it out with the suggested method at some point.
Let me know what you think
