Does anyone know why the ACPI namespace keeps changing? I had a script a while back on a Red Hat system which read the CPU temperature from '/proc/acpi/thermal_zone/THRM'. Now I have a new (but similar hardware) and relatively same distro (except for a few drivers here and there) and it has changed to '/proc/acpi/thermal_zone/TZ00' and '/proc/acpi/thermal_zone/TZ01'?
Is this even the CPU thermal? Or is it for something else?
I know most will say, read the ACPI docs... But that's beyond the point. Why and who keeps changing the namespace?
