ldconfig weakness
Ok, ok, sorry for my misapprehension. So, so ldconfig!
I checked the net again and could not find any postings from Jeremy Tregunna from 1994 or before. There are only the 24 hits, known from the former search for libconfig, the oldest starting with 2004.
Anyway, there was praised ldconfig as a solution, surprisingly it has grown now to a problem. But as I gamed a little bit around with it now, I really think there is some likeliness that there really is a ldconfig-problem as a source of that libiovmall.so-problem in all debian flavours.
Tnx for the hint.
