The next uploads will probably (unless I stumble across any problems) be
linked against libsensors4.

As this has come up a couple of times and the debugging output did help
debugging quite a few problems so far, I'm thinking about providing some
collectd binary with debugging enabled in Debian.

Are you sure this is caused by the "hddtemp" plugin? If either the
"rrdtool" or "csv" plugin is enabled the daemon writes to the disk every
