What are you expecting

This should pretty much explain it

@Viacheslav sure, updated the OP

Just a heads up that the above script can potentially destroy the config on boot, because if the system is fast enough, the hook will run before the boot config has finished loading. This will result either in an error when commiting because the config is locked (good outcome), or the config not being loaded at all (bad outcome). I've changed it a bit to actually wait for the boot config to load and now it runs safer, but it's still a bit janky in my opinion, I'm still hoping we can get something that works in-system for this case
