Bug#778701: Wrong disk usage displayed

[jnqnfe]

Control: close -1
thanks

I have since discovered that was a result of the 5% reserved space
feature, and affects more than just gnome-system-monitor.

I have to say, as someone relatively new to linux, not knowing such a
feature even exists, it is pretty confusing for various tools and
interfaces to display conflicting and confusing information about disk
space availability/usage with no explanation about this.

If a tool is going to display information about only space available to
the user (excluding the 5% reserved), then it should do so for all
number presented, not just some of them. Perhaps it might even be
helpful to display a '% reserved' column, to give a very helpful hint as
to what is going on regarding any missing space that the user expected
to have and to explain differences in output of different tools.
