It think eventually we will need some kind of trouble-shooting
FAQ or manual, but at this time it seems the incidents where that
problem manifests are rare enough that we can deal on the list
with it. I have been thinking for a while about splitting up
the FAQ though, but at the moment I simply do not have the time
to it right. Maybe later this year.
