Regression in coreutils df - does not show some mounts including root

[jblachly]

Pkgsrc 2015Q4

GNU coreutils df does not show many mounts, including the root filesystem, which is inconvenient.

Hm, explicitly asking for df / works though, and df -a works but doesn't get the stats right.

This seems to have been fixed meanwhile. At least df 8.25 in the just released 2016Q3 branch works fine:

I'll verify by backporting to the 2015Q4 LTS branch.

Ah, @jperkin already backported the update and df works fine in 2015Q4 now. Closing.
