Hrm ... we could let the 'unixsock' plugin check an already existing
socket file for a matching owner and group (possibly only if that is not
root.root) and whether it's an unused socket (is that possible somehow?)
and then, on successful match, remove the file on startup.

That does introduce some magic but this way it should be fairly save to
remove the file (remember: collectd runs as root in a lot of, possibly
most, cases).

Any thoughts on that?

Cheers,
Sebastian
