Hi!

It seems /proc/acpi/battery interface is gone, and I don't see any
option to reintroduce it... what is going on?

The interface went away in a semi-recent kernel release (3.13 or
3.12), breaking pretty much every battery app. (Admittedly the
interface was marked as deprecated for quite some time, but that
didn't stop everyone from using it and not caring about the new
thing.) I've yet to find a windowmaker dock app that works with the
current sysfs API :(

Looks like this one is the said commit.
If it breaks userspace we have to revert it IMHO.


Yes, we will revert the commit if it really breaks some APPs.
