I know how awkward that title is and I apologize.

OS: Home Assistant 11.2

Core: 2023.12.3

Computer: Raspberry Pi 4 Model B Rev 1.5

Explanation: I run a set of data collection scripts on my home network and one of the pieces of data is getting the computer model. In all my other SBCs, the below symlink gets that data.

Symlink: /proc/device-tree/model

File Location: /sys/firmware/devicetree/base/model

The symlink is broken and when I went to check the firmware directory, it is completely empty. The last update date for /sys/firmware according to ls -la is December 10 at 2:40 which when I checked my backups, is when core_2023.12.0 installed.

Attached is what should be in the firmware folder on my other Raspberry Pi 4 Model B Rev 1.5 right now.

I did a find from root for either the model file or anything vaguely resembling it and I can't find it. Anyone else have this problem or is it just happening to me? Or am I missing something?

I know, I'm trying to write up a clear bug report on this, but I'm honestly not sure if it actually has any effect other than messing up my data collection scripts. Yeah, it's annoying the hell out of me but I've been going through the documented issues with the core and it doesn't look like anyone else noticed a problem. I've been trying to figure out if it's created by an alpine package that I can run, but not much luck there.

Note: I enabled root for Home Assistant OS and the symlink and file are fine there.
