So I need to do this for local mounts, or for all mounts? I have /, home, two
windows partitions and some nfs mounts.
The reason I want to try it is that the laptop appears to be running much
hotter under KDE4 than it did under KDE3, so I want to test whether
over-frequent updates is the reason or not. For instance, if I minimise this
message then maximise it again, the fan will start. Obviously, if there was
a problem with the temp mounting I would take it out again.
