Hmm. Oh, well. It is not that important. But I really hate this badly documented obscure "automagical" stuff. As soon as anything breaks, it really sucks. On the side of where cryptsetup finds the device for a specific major and minor number, it is indeed a simple recursive directory traversal. Unfortunately it is in libdevmapper.c, i.e. in the system lib of that name. That means it cannot easily be changed. Arno -- Arno Wagner, Dr. sc. techn., Dipl.
