Having had a bit of time to think about it, it seems that it would indeed be necessary to store the device name. A possible alternative is to traverse all of /dev/ and report all devices that match major/minor. This may be the solution causing the least effort, as cryptsetup is doing something like it already, just that it currently stops after the first match. In fact, I think I prefer for it to report all devices that match. Arno On Wed, Jan 13, 2010 at 11:20:36AM +0100, Sven Eschenberg wrote: > Hi Luca, > > I doubt this is possible.
