Greetings
Someone has performed an act of hacking IO performance information
collection from the kernel.
iotop and iotop-c don't collect IO wait information anymore unless one
"opts in" by setting up the relevant variable in /etc/default/grub. This
is the wrong way round for running a server.
If someone is that desperate for space/time then they can opt out. The
rest need to know what is going on in a busy system and there is plenty
of CPU etc to collect said information.
It should be changed back to how it was and more oversight done to
prevent such changes creeping in.
