Yes, right. All not completely new systems, all completely new slackware 
and derived systems... "relatively" is a word very much needed here.

I really cannot believe you guys are actually arguing this. It seems 
that me being tired and short pulled this in to senseless country but 
can we please concentrate on the issue?

libsensors dictated the ABI rule that the hwmon directories must have 
device backlinks; the new ACPI Thermal Zone hwmon interface breaks that 
bit of ABI. It is not relevant that that ABI may have gotten to be as a 
result of unfortunate programming on the userspace side -- the only 
thing relevant is that it IS. lm-sensors 2 is on millions of systems out 
there. This is not meant agressively, or whatever you guys seem to want 
to read in my words, it's un undeniable fact.


At times there can obviously be situations where it's fine to require 
new userspace but in this case we have a new userspace which hasn't even 
been released yet, we have a ton of _different_ userspace depending  on 
that bit of core userspace, we have breakage of the important kind (as 
you no doubt know, sensors can be pretty vital, although admittedly it's 
not silent breakage at least) and we have an opportunity to just say 
"okay, we'll apply a 1 line patch and be done with it" which avoids any 
and all problems. Why are you arguing this?


This cannot be the reason, because it's not wrong. We just need a device 
backlink. Basically, any single one will do. It's just about keeping 
lm-sensors 2 happy.

Rene.
