The console user already got these rw rights otherwise e.g. nautilus-cd-burner wouldn't be very useful. For instance, today I may mount a filesystem from a CD-RW and then erase the disc at the same time (which should be fixed by putting some brains into the CD burning/erasing software; e.g. check if (parts of) the disc is already mounted; maybe it's already there, dunno). > I've no strong opinion either way but if it is changed in an update it > needs good documenting and might also need a kernel detail fixing > Can you clarify what kernel fixing is needed? It is my understanding that only DVD-RAM drives with DVD-RAM media will allow one to mount a filesystem rw (for optical drives) - is this correct? Thanks, David
